Celiac.com 10/16/2008 - Having gone gluten-free I, like many of you,
have been struggling with gluten-free baking challenges. I began with
pancakes. My first pancakes, made with a popular mix, were not the
light, fluffy things that I remembered. My son compared them to hockey
pucks. They got eaten, but were not a favorite. The next time I tried a
popular author's gluten-free pancake recipe. These were a hit, and did
not have the sourness of the popular mix (which were bean-based)! The
author's recipe was also based on sorghum flour, so I have become
convinced that sorghum holds the greatest potential for gluten-free
baking. I also tried the author's recipe for bread, which is based on
her same sorghum flour mix as her pancakes. The bread, however, was a
disaster, and it collapsed as soon as it was taken from the pan. I
think possibly that the problem was that by the time you take her
sorghum flour mix, and add the additional potato starch called for in
making the bread mix, you end up with a mix that is overwhelmingly
starch rather than flour. There is actually very little sorghum flour
in it by that point. I repeated these problems when trying to use yet
another popular sorghum-based gluten-free bread mix.
Meanwhile,
in my search for a good sorghum bread recipe I kept coming across a
blurb by the Agricultural Research Service to the effect that they had
discovered that sour dough fermentation improved the quality of sorghum
bread. Well, I have never been fond of the sourness of sourdough bread,
but I was interested to know that the ARS was trying to find good
recipes for sorghum bread. Apparently they are convinced, as I am, that
it holds the highest promise for good gluten-free bread.
Well,
heck, the Agricultural Research Service was my old stomping ground! For
a couple summers during college I worked at the ARS in Beltsville,
Maryland, and at least one of them was spent in the Human Nuitrition
Research Division. I worked as a biochemical technician. While I was
working with test tubes and distillation apparatus, the wonderful
aromas from the nearby test kitchens would waft by me and I would envy
the taste testers. I decided to contact those sorghum researchers who
have been involved in the search for a good gluten-free bread recipe. I
emailed them requesting to know if they had developed any good
non-sourdough recipes, and I received the following replies (the reply
from Tilman Schober was particularly valuable):
Dear Hallie Davis,
There
are a couple of things which could help you to get the desired
gluten-free sorghum bread. Sourdough is not imperative, it just
additionally helps to stabilize the bread structure. But we know that
many people object to the flavor. So, besides sourdough, the following
things may help:
- 1) Add the hydrocolloid HPMC (hydroxypropyl methylcellulose).
It tremendously helps to get a good crumb. It is a food additive, and
some people object to it because they regard it as not natural.
However, it is available in a food grade version designed for human
consumption, and we simply know nothing that works better. Xanthan gum,
probably the second best hydrocolloid, is much inferior in gluten-free
bread making. There are various slightly different versions of HPMC
commercially available. As US government employees, we cannot endorse a
specific product. However, I would like to let you know that we had
good success with Methocel K4M, food grade, which is available from
retailers like Ener-G Foods.
- The larger your bread pan the more likely the bread will
collapse. Try to use small pans, and just bake more loaves. This also
helps to keep them fresh (just freeze the loaves which you do not eat
fresh immediately after cooling). A good pan size might be e.g. 6
inches by 2-3 inches and 2-3 inches high.
- Mix sorghum flour with starch. A recipe that has worked for us
is described in the attached article (wHPMC, p. 5138). It is as follows: 105
g water, 70 g sorghum flour, 30 g potato starch, 1.75 g salt, 1 g
sugar, 2 g dry yeast, and 2 g HPMC. Highest accuracy in weighing these
ingredients is not required, but I would prepare a larger amount of
dough (e.g. all ingredients multiplied by 10), so that it is easier to
weigh. Mix all dry ingredients first in a large bowl (make sure that
the HPMC is well mixed with the rest, it tends to form lumps with
water). Then add the water, mix (electric mixer) until a smooth batter
results, and pour (or spoon) the batter in the greased bread pans. Let
the dough rise for about 30-45 min (depends on temperature, observe how
it increases in volume) and bake at 355 oF for about 30 min (depends on
pan size, you will need to find out for your pan size and oven type).
Another source for sorghum recipes you can find here:

They sell a CD with recipes (it is copyrighted, so I cannot send it to you).
If you have success, we would love to hear about it. If you need further assistance, please let us know.
Kind regards
Tilman
Tilman
then wrote again, enclosing a copy of the referenced article, and
asking that I cite it. The article was published in the "Journal of
Agricultural and Food Chemistry", 2007, 55, 5137-5146, and is entitled,
"Gluten-Free Sorghum Bread Improved by Sourdough Fermentation:
Biochemical, Rheological, and Microstructural Background." The Authors
were Tilman J. Schober, Scott R. Bean, and Daniel L. Boyle. They are
working in the Manhattan, Kansas Grain Marketing and Production
Research Center of the Agricultural Research Center.
The other
person who responded to my inquiry was Scott R. Bean. He sent me an
earlier but related article, entitled, "Use of Sorghum Flour in Bakery
Products." This article was published in the "AIB International
Technical Bulletin" in Volume XXVIII, issue 3, May/June 2006. The
authors here were:
- T.J. Schober and S.R. Bean, USDA-ARS, GMPRC, Manhattan, KS 66502
- E.K. Arendt, University College Cork, Cork, Ireland
- C. Fenster, Savory Palate Inc., Centennial, CO 80122
This article had the formulas for two sorghum flour blends:
Sorghum-Corn Flour Blend and Sorghum-Bean Flour Blend. Further
references for the mixes and also a brownie recipe is given as:
- Fenster, C. 2004. Wheat-Free Recipes & Menus: Delicious, Healthful Eating for People with Food Sensitivities. New York: Avery (Penguin Group).
A
recipe for Sorghum Waffles was also given with a citation, "Recipe by
Amy Perry and Meredith Wiking, used with permission from
www.twinvalleymills.com." So, the ARS, like me, is using recipes
by popular authors and Twin Valley Mills as a starting point, and are
experimenting from there.
I don't know about you, but I, for
one, intend to get the Methocel K4M, food grade, and try using it
instead of guar gum or xanthan gum! I also plan to try the 70-30
sorghum mix described today by Dr. Schober. I am TIRED of gummy bread,
and collapses!
