How to Make Gluten

8 cups gluten flour (bread flour may be used)
2 1/2 cups water

Mix the gluten flour with water to make a stiff dough.
Form into a ball and knead well. Let stand underwater for at least 1/2 hour,
or overnight, if possible.
Wash out starch by kneading with the hand in the water, being careful to keep
the dough together. Pour off the starchy water frequently and continue washing until the water is almost clear. You will then have a lump of gluten.
Boil the lump of gluten in water with onions and soy sauce.
Refrigerate until needed.
