Fresh ground Gram Flour- also known as- Besan, Channa, Harina De Garbonzo. The recipes I use this in, call for only very small amounts, so I keep a bag on hand and grind as needed. It only takes a few minutes.
1 bag of dried chickpeas (garbonzo beans)
Add the beans to a spice grinder, food processor, or maybe a blender
( haven't tried it, I hear it works.)
Grind it into a powder and pour it through a sieve, to remove any large particles.
