How do you cook bean flour?
One delicious way to cook bean flour is to mix with water (and any seasonings you like) to form a savory pancake-like batter for fritters. Here's one Nigerian recipe using lentil flour, but other bean flours would work too.

Something delicious I started doing a few weeks ago... Mix garbanzo bean flour with salt, pepper, and seasonings (such as garlic powder, ground coriander, ground cumin, chopped cilantro, etc.). Combine seasoned flour mixture with water till thick and cake-like (about 2:1 ratio). Form into a block and cut into strips about 1cm square and 8cm long. Roll in garbanzo bean flour to lightly coat. Fry in coconut oil till crispy on both sides. Serve with a dip. (Curry sauce goes particularly well with them!) They're a bit like French fries.
