Three pounds wheat meal; half an ounce, avoirdupois, muriatic acid; hall an ounce, avoirdupois, carbonate soda; water enough to make it of a proper consistence. For white flour, four pounds of flour; half an ounce, avoirdupois, muriatic acid; half an ounce, avoirdupois, carbonate soda; water about a quart. The way of making is as follows: - First mix the soda and flour well together by rubbing in a pan; then pour the acid into the water, and mix well by stirring. Mix altogether to the required consistence, and bake in a hot oven immediately. The gain from this method of baking is as follows: -lour pounds of wheat meal made seven pounds nine ounces of excellent light bread; and four pounds of seconds flour made six pounds of excellent light bread. It keeps moist longer than bread made with yeast, and is far more sweet and digestible. This is especially recommended to persons who suffer from indigestion, who will find the brown bread invaluable. (See 461.)
