Chickpea flour is common in Indian cuisine. It’s got more fiber and protein than typical carb-heavy flours, though has a noticeable flavor.

You can choose between flour ground from raw or roasted beans. The former is a bit bitter, while the latter is nuttier.

I usually use it with garlic and onion to make flatbreads in the microwave. It’s also useful to thicken dishes with strong flavors.

Like lentils you may find better prices when searching by its native names: gram flour or besan.
