'Wood flour' -- subject(s): Wood products, Wood flour

You can eat wood, but I think the more appropriate question is

"Should I eat wood?"

The answer to that question is no, you should not eat wood!

Replacements or substitutes for all purpose flour are:

1 cup + 2 tbsp sifted cake flour = 1 cup sifted all-purpose flour;

1 cup minus 2 tbsp unsifted flour = 1 cup sifted all-purpose flour;

1 1/2 cups breadcrumbs = 1 cup sifted all-purpose flour;

3/4 cup whole wheat flour or bran flour + 1/2 cup all purpose flour;

1 cup rye or rice flour; 1/4 cup soybean flour + 3/4 cup all-purpose flour

After washing down a shire horse, the owner or groom hand will use wood flour to dry the feather on it's legs quickly, in preparation for a show.

1 tbsp of flour is about 8 gm.
