Hartshorn, maybe. I came across one reference to it as a (possible)
leavening agent. Other than that, I haven't found any chemical leavens.
Chemical leavens start appearing in the 18th Century. I don't remember
potash being referred to as a leaven, but pearl ash (potassium carbonate,
one of the types of potash) is.
In the Middle Ages, cooks appear to have depended on yeast (ale, grape must,
sourdough, etc.), whipped in air, and oven spring to lighten their bake
goods.

Hartshorn in the Middle Ages may have been precisely that, powdered horn
from a hart. Modern hartshorn is an ammonium compound, ammonium carbonate,
IIRC.

I've got to go with Bear here. While it appears to be the case that
chemical leaveners as we know them don't appear widely until the
nineteenth century, that doesn't mean that the chemicals used as
leaveners haven't been used for other purposes for thousands of
years. For example, soda --and note that "baking soda", or sodium
bicarbonate, may not even be what is intended here-- was used by the
Romans as a green color fixative and tenderizer for vegetables, just
as it sometimes is in recent European (esp. French) cookery. Modern
Chinese cookery also employs baking soda as a meat tenderizer,
usually for tougher steaks and tripe (you wash it off carefully
before cooking, like the lye solution in the preparation of
lutefisk). The Roman cooking soda appears to be what we call "washing
soda" or sodium carbonate, but I don't know which soda Dr. Buell is
referring to.
Ultimately, such chemicals seem to have been known to the medieval
Chinese, but whether they considered them rising agents is
questionable. Of course, modern steamed bun recipes also sometimes
call for both soda and yeast; it may be a habit so lost in tradition
we'll never know its origin.

I have a couple of questions that I suspect you guys may be able to
answer:
In one recipe, I encountered a reference to "leavening"....from de Nola:
Oranges from Xativa Which Are Crullers
Take fresh cheese and curds, and mash them in a mortar together with
eggs. Then take dough and knead the cheeses with the curds, together
with the dough, and when they are all kneaded and incorporated take a
very clean casserole, and add to it a good quantity of sweet pork fat or
sweet oil which should be fine, and when the pork lard or oil boils,
make some round masses from the aforementioned dough, like balls or
round oranges, and put them in the pot in such a way that the ball goes
swimming through the casserole, and you can make small rissoles from the
dough, or whatever forms and remarkable things you wish, and when they
take on the color of gold, remove them, and add a few more, and when
they are all fried, put them on plates, and pour honey over them, and
scatter ground sugar and cinnamon over them. But note one thing: that
you should add a little leavening to the cheeses and the eggs, and add
flour to the other, and when you make the balls grease your hands with a
little oil which should be fine and then take them to the casserole, and
once they are in if the dough crackles it is a sign that it is very
soft; and you need to add more flour until it is harder, and once the
dough is prepared and fired add the honey and sugar and cinnamon as is
described above.
What kind of leavening are they referring to? Could I get away with
using yeast?

In southern Europe, they tended to use sourdough as leavening, rather
than the ale barm that was used in northern countries. However, they
did not admire the sour flavor that comes from letting the dough sit
for a long time. (Platina warns against this in his bread-making
instructions.) If you don't have sourdough starter, you could use
yeast, but you would have to make a sponge, not add the yeast directly.
Dissolve about 2 teaspoons of yeast in 2 cups of warm water. Wait 10
minutes, then add enough flour to make a mixture like thick pancake
batter. cover, and let sit for an hour or two, until it is bubbling
happily. Use some of this sponge as the leavening in the fritter
recipe.

Presumably the recipe is calling for either sourdough starter or
barm, which would be skimmed or racked (depending on the yeast and
brew type) from actively fermenting beer or wine. Yeah, I think you
probably could use dry or compressed yeast, if you first mixed it
with a little water and maybe 1/2 tsp sugar, the way you often do to
get a "sponge" before baking with it.
I have a Latino (Colombian, I think) bakery a couple of blocks from
home, and they sell what I STR are called bunuelas that sound and
look nearly identical to what this recipe describes. In fact they do
look quite a bit like oranges. I like the detail in this recipe of
the oiled hands and the comment on the cracked dough, because it
seems likely you need to build a sort of gluten skin on each of these
as you form them. The standard technique used in some Greek fritter
recipes to achieve this would be to sort of squeeze a double fistful
of the dough out between the fingers into a round ball shape, which
you pinch off, leaving a smooth and unwrinkled surface to the
fritter, rather than that sort of convoluted surface that foods
rolled into balls can sometimes have. All I know is that when
fritters crack, they seem to tend to absorb lots of fat in the
cooking process, more so than when they don't crack, so this may be
why this is important. The ones I see in the bakery are pretty
astonishingly smooth and round.

Funnily enough, I discovered something just last week
regarding medieval leavening that you migh find
interesting.
While perusing Dawson's fine cakes recipe from The

Curious, I looked up the phrase "God's good" in th

the phrase is barm or yeast. :)

I have no idea. The French word is "levain". I didn't see any mention
of how the leaven is produced.
::pause to re-read chapter:: He says that the smallest and lightest
breads are made from a levai that contains one-sixth of the total
flour, plus very fresh ale barm ("leveure de biere"). In context, it
seems that this was not the leavening used for most breads. This
assumption is strengthened by the definition of "levuere" in the 1694
dictionry of the Academie Francaise: a foam produced by beer, which is
used to raise dough for a certain kind of bread.

Most French breads were made from continuous use starters. Until this
century, there was a law in France that prohibited the use of yeast. The
law was rescinded primarily because you need yeast to produce those
extremely light and crusty baugettes. I assume that the term used in the
original text is "levain" (if I remember the right spelling) which in the
context of 17th Century France refers a ball of dough (around 10 pounds or
so) the baker maintains to seed the sponge for a batch of dough.
Yeast is never added to the levain or (presumably) to breads made from the
levain. Yeast is used strictly for specialty breads.

What we are talking about is Saccharomyces cerevisiae, baker's yeast. In
other words, thou shalt not yeast thy bread with ale barm.
One needs to keep in mind that ale barm was used primarily in Northern
Europe (the beer and ale countries) while spontaneous starters are common to
the Mediterranean countries.

What you are after here is potash, potassium carbonate, which was originally

Lye (caustic potash) is the liquid produced by leaching wood ash containing
potassium hydroxide. Potash is the potassium carbonate produced by
evaporating lye in a pot. The chemistry is rather complex (which means I
don't fully understand the process), but drying the leach concentrates
carbonic acid that in turn produces a high percentage of potassium carbonate
in the solids. When exposed to water in the dough, the potassium carbonate
reverts to potassium hydroxide freeing carbon dioxide.
Use of the term potash in English begins in the latter half of the16th
Century, so its use in German and Dutch predates that.
The lye in German baking is as a solution brushed on the crust to alter the
crust in the baking process. Potash is used as a leaven. Without some
accurate records, there is no way to tell how the two are related other than
both result from leaching wood ash.

The leavening agents primarily used were ale barm (liqour from the active
ferment on the top of the ale pot) and starter. Malt was definitely not
used as a leaven. It can be used to feed a leaven or as a sweetener
depending on the quantity used. The earliest recipe I've encountered to add
malt to dough is in Markham's The English Housewife which is just out of
period and would place the practice in Elizabethean times.
I've used both malt extract syrup and powdered diamalt in bread. I prefer
the syrup for sweetening and the powder for boosting the fermentation.

Chemical leavens are meant to be used immediately. Starters develop over
time. Flour and water will create a starter. Soda and cream of tartar will
produce a leaven when hydrated. But the four ingredients together are only
good for producing soda bread.
Sodium carbonate is soda, now or then. It was used to tenderize vegetables
(Roman) or, apparently, as a flavoring agent in one Chinese bread recipe. I
know of no reference to it's use as a leaven. Sodium bicarbonate, the
modern baking soda, is preferred because it doesn't release all of its CO2
until heated. AFAIK, sodium bicarbonate was not used in period. Baking
powder is a combination of sodium bicarbonate and cream of tartar and
usually a third compound that releases CO2 at higher temperatures for
a good rise.
Hartshorne (probably ammonium carbonate rather than actual deer antler) was
used in Germany in the late 16th, early 17th Centuries as a chemical leaven
(still is for that matter), but it would probably not have been used
with a bread.
I've a number of different chemical leavens from the late 17th and 18th
Centuries, but no trails leading back into period.
Given a Mediterranean climate, the most probable leaven for bunelos is a
sourdough starter, but you can fudge it with baking yeast. If you want real
starter, try two cups of flour and one cup of water mixed together in a
bowl, cover with plastic, and leave it on the counter for a few days. One
cup of starter will leaven about 2 to 4 pounds of bread. Replace one cup of
the liquor in your recipe with one cup of starter.

Potash, also referred to as lye, and a name for several different compounds.
In this case, you're talking potassium carbonate rather than sodium
hydroxide or potassium hydroxide, which put the caustic in caustic soda. I

I've used it as a direct starter to make a sponge, and I've also
cultivated it as a starter (treating it as you would a jar of starter

Use it fast or feed it (water and malt extract).. If you don't, it will
die. There is also a possibility that it will be infected by mold if you
try to hold it. It is not a starter and will not keep like a starter. It
is a yeast solution equivalent to dry active yeast proofed in some

If you leave it alone without feeding it, and it escapes infection, you will
have autolysis to deal with. that is the death and degredation of the yeast
cells. You will get a very distinctive off-yeasty taste when this starts to
occur. We work with this in brewing a lot when making "aged" beverages.
You have to siphon the desired beverage of the yeast silt at the bottom
occasionally to prevent that yeast bite from autolysis.
If you want to keep it alive, boil some (quarter cup?) malt extract or plain
sugar in a cup of water. Cool it down and add to the yeast. That will keep
the reproducing and eating for a couple of weeks. You'll get CO2 release,
so don't seal the jar tight . . . put an unpowdered latex glove over the jar
with a tiny pinhole in one or two of the fingers (or a balloon if it will
fit). You'll want to pour off the liquid every three or so weeks to keep
the dead from breaking up in it.
You might get a few weeks out of it, but the chance of a bacteria or mold
grows with every time you open it to feed it. He didn't give you an

I've used it a number of times, and find that the rise time needed varies
significantly based on the strain of yeast my husband has used.
I've also had a perenial problem with a bitter flavor that we've attributed
to the hops. I hadn't yet tried it with his gruit ale, as he doesn't make
it very often. It doesn't seem to matter if I use the barm from an actively
fermenting vessel or the trub after the ale has been racked off, the problem
remains. I've washed it, run a two-generation starter, etc., and still have
the bitterness to one degree or another. I'd be grateful for wisdom from
wiser heads than mine!
That said, I have a starter on my counter made from an English Cider yeast
that is doing fabulously. It seems to be attenuating to life in flour and
water and gets more reliable with time. Either that, or it's gotten
contaminated with the regular bread yeast in my bake-happy kitchen and
that's slowly taking over. No bitterness issue with this one.

"Massa" means dough, but in this case it is dough retained for leavening as
you state. For home baking, the "pinch" of dough is a lump about the size
of your fist, approximately a cup. For a commercial baker, it is likely a
ten pound football of dough.
Rather than being simply added to the new dough, the massa should be broken
apart in the liquor for the new batch, then mixed into the flour. This
ensures that the spread of the yeast and lactobacilli through the dough. In
commercial baking, this step would be used to create a sponge from which the
starter would be recovered, then the sponge would be broken apart in liquor
and added to the dry ingredients to form the actual dough, preventing
contamination of the starter by any of the other ingredients of the bread.
Whether or not this procedure was used by the commercial or home bakers
within SCA period is unknown.
A second rise is not necessary to producing bread and I have found no direct
evidence as to whether the second rise was a baking technique used in
period. The appearance of a dough box in a 16th Century woodcut of a
baker's shop suggests, but does not confirm the use of two rises. Second
rise was well established by the mid-19th Century and I'm still in the
process of tracing its use.

My research suggests that northern Europe with its beers and ales more
commonly used ale barm while the Mediterranean countries tended to use
sourdough starters until modern manufacture and refrigeration made yeast
commonly available. The use of ale barm as leavening was introduced into
Italy in the 2nd Century BCE by Gallic bakers, but apparently fell into
disuse as the empire declined.

Almost certainly. Dough troughs appear in the household inventories of

I can see adding borax as a tenderizing agent, but I question the leavening.
The chemical leavens I'm most familiar have a CO3 molecule that converts to
CO2 and water. Borax is NA4B2O7. During disassociation (if I got the term
right), I would expect the O7 to recombine as H2O rather than O2. The
fastest way I know to test would be prepare a recipe and see what
happens.
We discussed a similar issue in Soup for the Quan. I believe the discussion
is in the Florilegium and includes Paul Buell's response to our
comments.
I've never heard of using borax as a leaven, so it would be interesting to
see if this is the author's interpetation or if there is source material
that supports the use.

And, we also need to be really, really clear, when we speak of

referring to hartshorn, the gelatin source, made from powdered horn

Oddly enough, I just found an interesting website which essentially
claims that the use of hartshorn salts as a leavening agent have a
linked history to that of the development of baking powder, and that
both are 19th century innovations based on attempts to specifically
create chemical leaveners, whose primary advantage was considered to
be that, unlike yeast, they don't break down and eat up to 3% of the
flour they're leavening.

What has me a little concerned is that although I keep seeing references

I'm seeing references to the references, "we all know that" such-and-such

looking at a slightly more benign version of the Big Lie political
tactic, an untruth which, if repeated often enough, becomes widely
accepted as the truth.
Can anybody cite some specific, clear, primary or near-primary source
reference to hartshorn as a leavening? It would presumably have to be the
ammonia salt, and not simply the ground-up horn, which, as I recall, does
appear in jelly/leach recipes as a gelling agent, like pig's feet, cow
hooves, isinglass, etc.
The fact that we've been talking about this here on SCA-Cooks for a

-----------------------------
An excellent considration. Somewhere among my papers, I have what purports
to be a translation of a recipe from the 1590's that uses hartshorn as
leavening. I have yet to find the source to determine if it is an accurate
translation or modern fudging of an older recipe. If I can locate it, I'll
post it. Beyond that, my personal collection of recipes has mostly mid to
late 19th Century recipes with chemical leavens.
Root suggests that actual hart's horn was used as a leaven in the 16th
Century and was replaced by ammonium carbonate. I'm not sure how to produce
an edible leavening gas from bone, so this statement is questionable, until
proven or disproven.
The Oxford Companion to Food, under baking powder. give a 1790 date for the
use of pearl ash as a leavening agent prior to the creation of baking
powder. No reference to hartshorn.
It is worth noting neither source provides a primary source for the

I have wondered about this for years, I
could never figure out how an antler gave anything like a chemical rise.
I found this on OChef's Q&A page. They suggest heating (not 'burning', just
'heating') releases the gas that produces the leaven.
"Hartshorn is a leavening agent, and a precursor to the baking soda and
baking powder that everyone uses these days. Hartshorn's virtue is that it
readily breaks down into a gas when heated (causing the leavening), but
unless it escapes completely, it leaves a hint or more of the smell of
ammonia. For that reason, it is generally used only in cookie recipes where
it doesn't have to fight its way out of a deep batter."

Curious. Sodium tetraborate decahydrate (borax) shouldn't react in a way to
act as a leavening. It is, however, a water softener and as such could
improve the quality of the bread. I note that it is used with yeast and not
as a separate leaven.

I knew I had seen information on water hardness and gluten formation. There
is an entire section in Paula Figoni's How Baking Works.
According to Figoni, minerals harden gluten, making the strands so elastic
that they don't stretch properly to trap the CO2 in fermentation. The
higher the gluten content, the worse the problem. When you reduce the water
hardness, you reduce the spring back in the gluten strands and allow them to
properly extend.
The most common minerals in hard water are calcium and magnesium. Borax
will react with calcium and magnesium in solution neutralizing the effect on
the gluten (I suspect the minerals will precipitate out and become part of
the solid matrix, but I haven't researched that). Interestingly, desert
regions often have hard water. Northern China, North Africa, the Middle
East?
There is also a pH factor involved, calcium carbonate being on the acidic
end of the scale and borax being basic, but that's a little different from
the issue of hardness.
Next time I'm in NM, I'll try adding a little baking soda to the mix to see
if I can get a better rise.

I've been reading al-Warraq and am still puzzled over the borax question.
According to the author and the translator, there are two kinds of
borax: Natron and baker's borax (aka Armenian borax). The latter is used
in food, both to make a glossy surface on bread and, apparently, as a
leavening! The translator says that it is sodium borate, which is what
is now called borax--and never explains the chemical difference between
the two kinds, although she does describe their differing appearance.
But according to Wikipedia, natron doesn't have any boron in it. It's a
mixture of sodium carbonate decahydrate and about 17% sodium
bicarbonate--aka baking soda. Which suggests that perhaps bakers' borax
is baking soda, or some natural mineral that consists largely of baking
soda.
In which case we not only have a period chemical leavening, we have
period baking soda!

E.J. Brill's First Encyclopedia of Islam 1913-1936, list several other types
of "borax." Obviously, borax is being used as a generic name for a number
of naturally occurring compounds rather than as a specific mineral, sodium
borate. The translator is correct, as far as the translator goes.
As for natron, the primary constituent is soda ash, sodium carbonate, which
is a natural water softener. There are modern bread recipes which call for
both yeast and buraq, suggesting to me that it may be the water softening
properties that are desired. As a generalization, soft water makes better
bread. At 17 percent, you would need roughly 2 Tablespoons of natron to get
1 teaspoon of sodium bicarbonate, so again I would think that the intent was
to soften the water with the added benefit of a little chemical leavening.

The translator says that it is sodium borate, which is what is now called
borax--and never explains the chemical difference between the two kinds,
although she does describe their differing appearance.
But according to Wikipedia, natron doesn't have any boron in it. It's a
mixture of sodium carbonate decahydrate and about 17% sodium
bicarbonate--aka baking soda. Which suggests that perhaps bakers' borax is
baking soda, or some natural mineral that consists largely of baking soda.
In which case we not only have a period chemical leavening, we have period
baking soda!

al-Warraq is pretty explicit that it's leavening. In one of the
recipes, discussing what can go wrong, he mentions the possibility of
dead yeast and suggests adding more buraq to make up for it.
"If the yeast was bad, add some more borax to the batter." (p. 415)
Nasrallah says it was also used to give bread a shiny surface, but I
don't think there are any recipes in al-Warraq that do that. Any guess
what that might imply about the nature of bakers' borax?

That is an excellent quote. I obviously need to add a copy of the work to
my collection.
While I haven't used sodium carbonate this way, potash, potassium carbonate,
is often used in German baking to glaze pretzels and breads. Dissolve a
small amount in water and brush it onto the crust before baking.
Thinking about this after imbibing my coffee, I realized that, sodium
bicarbonate aside, any of the carbonates will, in the presence of water or
an acid, will produce CO2 for leavening. If you use water, the hydroxides
produced by the reaction may impart a soapy taste to the bread, which can be
counter-acted by using enough weak acid, sour milk, lemon juice, etc., to
neutalize the hydroxides.
The fact that al-Warraq knows natron to be a leavening agent, suggests that
a similar use of carbonate (IIRC) in Soup for the Qan may also have been as
leavening rather than as a tenderizing agent as discussed a few years ago.

You are thinking of lye in a modern chemical context where the word commonly
refers to sodium hydroxide but may also refer to potassium hydroxide. The
lye used in period German baking was hydrated from potash (potassium
carbonate) which is produced by leaching hard wood ash then boiling the
liquid to produce a residue (potash). In solution, potash breaks down into
potassium hydroxide, carbonic acid and carbon dioxide. Modernly, the term
potash has been used to describe a number of potassium compounds that are
not within the original definition.
Thinking about the chemical breakdown and looking at a couple of references,
David is probably correct that it is the alkaline solution that produces the
glaze and darkens the crust. If it is the base, then it shouldn't matter
much whether one uses sodium hydroxide or potassium hydroxide.
Still it sounds like some fun experiments to see just what just what kind of
crust the different compounds produce.

"Buraq" is a very general term and Brill shows more than two usages. It
appears that the collective reference is to any whitish crystalline
substance which can be used as flux in soldering. Armenian borax (modernly)
appears to be borax pentahydrate while US borax is borax decahydrate neither
is of use as a chemical leaven. The first usage of the term Armenian borax
is in a Coptic manuscript roughly contemporary to al-Warraq (IIRC). I have
seen no evidence that bakers' borax and Armenian borax are synonymous.
Redhouse's "A Turkish and English Lexicon" most helpfully defines "bakers'
borax" as "soda used by bakers". Oh, thank you for that insight. I really
would like to find an accurate usable definition.
I doubt if baker's borax is pure sodium bicarbonate (baking soda), which was
first produced in 1791, but some form of sodium carbonate with a small
percentage of bicarb (like natron) is certainly possible. The leavening
effect would not be as pronounced as with pure sodium bicarb. Sodium
carbonate alone would produce the glazing effect on the bread and might
provide a very minimal leavening.

Ammonium carbonate and sal ammoniac (AKA hartshorn or salt of hartshorn)
were originally derived from red deer (Cervus elaphus) horn by dry
distillation. Hartshorn makes a limited appearance in German baking toward
the end of the 16th Century, but it in more common in 17th and 18th Century
baking. It was largely replaced by baking soda.

Subject: [Sca-cooks] Hartshorn Re: Reasons why period cakes aren't
modern cakes
There is a recipe for "Water of harteshorne" in Heironymus Brunschwig's The
vertuose boke of distyllacyon of the waters of all maner of herbes, 1527. I
suspect this is an English translation of his Liber de arte distillandi
simplicia et composita (Little book of distillation) published in 1500. The
recipe is one of simple distillation of broken horn in water.
English sources, just out of period and beyond, use the antler as a source
of gelatine. As far as I can determine this is produced by the simple
process of breaking up the antler and boiling it to extract the gelatine
rather than true distillation.
Oil of hartshorn is produced by destructive distillation, where antler is
sealed in a container and then heated to break down the antler into
constituent molecules. It is pyrolitic process similar to coking or
cracking. Salt of hartshorn, a mix of sal ammoniac and ammonium carbonate,
is the extract of the condensate from distilling oil of hartshorn without
additional liquid (dry distillation). Salt of hartshorn is the original
chemical leaven. Also, there is the question of dating the use of these
processes to produce hartshorn in period. Modernly, ammonium carbonate,
baker's ammonia, is produced by mixing ammonia and carbon dioxide.
I have a translation of a German recipe that purports to be from 1590 which
uses hartshorn as a leaven. I have yet to locate the source of the recipe,
so it is of questionable provenance. Other than that, I have no particular
evidence of hartshorn being used as a leaven in period.
Baking with hartshorn produces ammonia and a strong odor of ammonia which
limits its use to thin bake goods which allow the trapped ammonia to
disipate. Because of this, the recipes which use it are likely to be small
cakes. I would expect to find it in a recipe for Springerle, a cookie which
uses hartshorn modernly and whose origin dates back to 14th or 15th Century
Scwabia. Unfortunately, the earliest Springerle recipe I have located is
Austrian from 1686 and does not list hartshorn.

That's what I found, too, on Wikipedia. However, I wonder if that was
done in period. There was a query on a Twitter account ( at tudorcook) that
I follow where someone asked how hartshorn was prepared for use.
Tudor Cook mentioned that "most of the recipes seem to call for boiling
6+ hours or...overnight before letting cool, straining then..." There
also was mention of rasping, perhaps before boiling. The inquirer was
Dr. Annie Gray and I don't know what the results of her experimentation
were. If an actual answer to the experiment is wanted, I could try to
find out."
