I was most intrigued when I came
across the idea of using snow as a leavening agent. The concept is impossible for me to test, as
I live in the sub-tropics, so I will have to rely on the advice of those of you
who live in the cooler parts of the world.
It seems that the idea captured
some interest in the 1850’s and 1870’s, in the United States. The Water Cure Journal (an early ‘healthy
lifestyle’ publication) in 1854 had this to say:
Snow Bread. - All persons where snow abounds, are not, perhaps, aware
of the value of the "fleecy flakes" in making light, delicious, and
wholesome bread. There is no "raising" in the world so perfectly
physiological as good, fresh, sweet snow. It raises bread or cake as
beautifully as the best of yeast, or the purest acids and alkalies, whilst it
leaves no taint of fermentation like the former, nor injurious neutral salt
like the latter. Indeed, it raises by supplying atmosphere wherewith to puff np
the dough, whilst the other methods only supply carbonic acid gas.
During the late snow freshet with which our city
has been favored, (for all other uses in a city snow may be regarded as
a nuisance,) "our folks" have experimented somewhat extensively in
the matter of snow-raised bread and cakes. One of our kitchen amateurs gives us
the following recipe as the result -the eureka - of his numerous mixings and minglings of
the "celestial feathers" with the terrestrial meal:
"Snow Bread.—Mix
equal parts of light, dry snow and flour or meal quickly together,
(using a strong spoon or stick to stir with.) When well mixed, pour the mass
into a pan, and bake immediately. A rather hot, "quick" oven is
essential. Bake from twenty minutes to one hour, according the thickness of the
loaf."
Many forms of bread and cake can be made by slightly
varying these proportions, according to the other ingredients: the rule being
to have a due degree of moisture. If too much snow is used, the bread or cake
will be heavy.
A little corn meal and pulverized sugar may be mixed with
dry flour, and then the snow stirred in, if a short and tender, as well as
light sweet cake is desired.
Apparently
the method works well for corn bread too. I give you a snippet from the
A contributor to the English Mechanic And World Of Science in 1879 wrote of his
experiences with snow bread, briefly described how it was made, and attempted a
scientific explanation:
I have this morning for breakfast, partaken of a
snow-raised bread cake, made last evening as follows: The cake when baked
weighed about three quarters of a pound. A large tablespoonful of fine, dry,
clean snow was intimately stirred with a spoon into the dry flour, and to this
was added a tablespoonful of caraways and a little butter and salt. Then
sufficient cold water was added to make the dough of the proper usual
consistence (simply stirred with the spoon, not kneaded by the warm hands), and
it was immediately put into a quick oven and baked three quarters of an hour.
It turned out both light and palatable. The reason appears to be this: the
light mass of interlaced snow crystals hold imprisoned a large quantity of condensed
atmospheric air, which, when the snow is warmed by thawing very rapidly in the
dough, expands enormously and acts the part of the carbonic acid gas in either
baking powder or yeast. I take the precise action to be, then, not due in any
way to the snow itself, but simply to the expansion of the fixed air lodged
between the interstices of the snow crystals by application of heat. This
theory, if carefully followed out, may perchance give a clue to a simple and
perfectly innocuous method of raising bread and pastry, and stop the discussion
as to whether alum in baking powders is deleterious to health or otherwise.
OK, you food
science geeks out there. Is this it? Does it work? Is snow bread simply a form
of soda bread? Please, do let me know if
you try this.

"Is snow bread simply a form of soda bread?"
ReplyDeleteIt's not that because you're not using soda.
Presumably it's just a way of introducing voids in the cake since the batter would cook to a certain extent before the snow would melt. (This would be why it says to use a hot "quick" oven.)
Dorothy Hartley (_Food in England_, 1954) mentions snow pancakes:
http://www.amazon.com/Food-England-Dorothy-Hartley/dp/1856054977/
I guess it's the same idea. She says use an ordinary pancake batter and stir in a spoonful of fresh snow just before frying.
Obviously, a pan- or griddle- cake cooks a lot faster than an oven-baked cake. So this, again, is "quick" cooking.
I've never tried it. I guess crushed ice would work just as well. One could put some ice cubes in a plastic bag and smash them with a rolling pin.
It would be an interesting experiment. On the whole I think bread is better raised with a (long) yeast fermentation -- or even better leavened with sourdough. The latter is (mostly) a lactic fermentation (but there are also some wild yeasts present in sourdough cultures) as opposed to an alcoholic fermentation (which is what you get with yeast).
Lactic-fermentation is good because it deals to some extent with "anti-nutrients" in the flour and makes the resulting bread more digestible. More here:
http://www.westonaprice.org/food-features/living-with-phytic-acid
A fermentation with yeast will deal with the antinutrients to some extent -- as long as the fermentation is long enough. Traditionally, bread was given a long time to raise (which, of course, gave it a fuller flavour as well). The infamous Chorleywood Process (see, e.g., Wikipedia) invented by British food scientists in the 1960s is a much faster process and has largely taken over bread making on the industrial scale.
Wow! Thanks Mike for that comprehensive review. I considered the soda bread anaolgoy because of the 19th C writers discussion of the compressed air in the snow acting 'the part of the carbonic acid gas in either baking powder or yeast'.
ReplyDeleteBut I am not a food scientist.
Thanks for reminding me too of Dorothy Hartleys snow pancakes!I knew I had seen snow used in some other recipe, but couldnt for the life of me remember where it was.
I have no erudite contribution to add to the discussion of Snow Bread. I am a skeptic, however, and in my forty years residency south of the Manitoba Canadian border, I have encountered no mention, plate, or basket of snow bread.
ReplyDeleteMy first hand experience with snow food comes from the coldest winters (not as frequent these days, thus bragging rights become scarce).
Carefully stepping outside from a warm, humid kitchen with a boiling hot pan of syrup, proceeding quickly and directly to a clean snow bank, one has drizzled steaming syrup on squeeky, dry snow, the harsher the cold the better. The maple syrup seizes into a taffy-like consistency almost instantly.
Properly dressed for survival at the lowest of temperatures, one then harvests the snow taffy from its sunken trail and most likely enjoys a little alfresco winter dessert.
Highly recommended.
I assume the bread works because the snow is frozen when it goes in the oven. As it melts it creates steam, which creates a pocket of air, unlike unfrozen water, which would simply melt into the dough.
ReplyDeleteButter works this way to create flaky pie crust. Chilled butter is essentially to keep the fat from melting into the dough. As the pie crust bakes, the butter melts and creates steam, which in turn creates little air pockets, making the crust light and flaky.
And I assume "dry" snow is indicated because a heavy wet snow would melt into the dough before the bread was baked.
Going to have to try this next time we get a nice, fluffy, dry snow!
For tiny snow crystals to melt when the dough goes in the oven would mean that the dough would have to be very cold during the mixing in, wouldnt it? I cant imagine it lasting long before it melted. None of the instructions indicate cold dough and quick handling. It does sound like an explanation tho'!
