Besan, aka gram flour, is a fairly common ingredient in India, though not in my particular region. The main things I know of that are made with besan are
Crisp golden potato and onion bites cooked with a selection of spices in a gram flour batter which are deep fried. ... I cook pakora in a number of different ways, either with onion and potato or a mixture of vegetables; onion, potato, aubergines and cauliflower.
The besan laddu prepared with this recipe gets its unique and mouth watering flavor, taste and aroma from ghee, roasted gram flour and generous use of saffron and cardamom.
