"_Hardtack_ (pilot bread, ship biscuit) can be recommended only for such trips or cruises as do not permit baking. It is a cracker prepared of plain flour and water, not even salted, and kiln-dried to a chip, so as to keep indefinitely, its only enemies being weevils. Get the coarsest grade. To make hardtack palatable toast it until crisp, or soak in hot coffee and butter it, or at least salt it. "Swedish hardtack, made of whole rye flour, is good for a change. "Plasmon biscuit, imported from England, is the most nutritious breadstuff I have ever used. It is a round cracker, firm but not hard, of good flavor, containing a large percentage of the protein of milk, six of the small biscuits holding as much proteid as a quarter of a pound of beef. "_Flour_--Graham and entire wheat flours contain more protein than patent flour, but this is offset by the fact that it is not so digestible as the protein of standard flour. Practically there is little or no difference between them in the amount of protein assimilated. The same seems to be true of their mineral ingredients. "Many campers depend a good deal on self-raising flour because it saves a little trouble in mixing. But such flour is easily spoiled by dampness, it does not make as good biscuits or flapjacks as one can turn out in camp by doing his own mixing, and it will not do for thickening, dredging, etc. "Flour and meal should be sifted before starting on an expedition. There will be no sieve in camp." "_Baking Powder_--Get the best available powder, put up in air and damp-eight tins, so that your material will be in good condition when you come to use it in camp. Baking soda will not be needed on short trips, but is required for longer ones, in making sour-dough, as a steady diet of baking-powder bread or biscuit will ruin the stomach if persisted in for a considerable time. Soda also is useful medicinally. "_Cornmeal_--Some like yellow, some prefer white. The flavor of freshly ground meal is best, but the ordinary granulated meal of commerce keeps better, because it has been kiln-dried. Cornmeal should not be used as the leading breadstuff, for reasons already given, but johnnycake, corn pancakes, and mush are a welcome change from hot wheat bread or biscuit, and the average novice at cooking may succeed better with them. The meal is useful to roll fish in before frying.
