i would thank so
In general, yes.
You use a regular bread recipe and substitute half of the flour with whole wheat flour.
yes you can adjust the water
You can use other types of flour. (White, wheat, bread, cake, ect.)
Teff can be used as a substitute for wheat. If you are making injera bread but teff flour is not available, you can use wheat flour, rice flour, or barley flour.
i suggest to use flour batter ins ted of egg batter which can be substitute just mix some flour and water by whisk. which will be help for coating bread crumb
If you add wheat gluten to your recipe, maybe a tbsp or so (depending on how much flour? tbsp per 1 or 2 cups of flour?), that will serve as a substitute. Most often you can get good results with the substitution. Bread flour has more gluten and thus holds more CO2 from the yeast to make fluffier breads.
It depends what your making. If your allergic there is many different types of flour, if you are short in some in a recipie, id have to know the recipie to make an accurate jugment on a substitute :) btw im 13
Not to bake stuff like bread. You can substitute 1 baking soda for 2 baking flour to make reductions. You can substitute 1 baking soda for 1 baking flour for gags (throwing on someone in the shower).
Bread crumbs, cracker crumbs or crushed corn flakes.
If by 'bakers flour' you mean self rising flour, the answer is no. Self rising flour has baking powder which causes it to rise. With crepes, you want them to stay thin and delicate, not to rise and have a bread-like consistency.
