Swastik Besan, also called gram flour, is made from channa dal, dried chickpeas and is a staple ingredient in many Indian and Pakistani foods. Some people may be more familiar with the name garbanzo beans for chickpeas, and further, others may confuse besan, with gram flour.
You will also occasionally see besan called ground chickpea lentil flour. It is actually the case that a variety of beans are called lentils, but in this case, besan refers exclusively to what we commonly refer to in the English-speaking world as garbanzo beans.
You will find numerous recipes that use the exceptionally high protein and gluten-free besan. It's used as a coating on many of the deep-fried favorites of India including the mouth-watering vegetable fritters called pakoras.
Many Indian curries are most authentic when they include besan to thicken the curry sauces that coats vegetables. Besan is used as a thickener in soups and sauces of all types.
