Pesarattu is a dosa like preparation native to Andhra Pradesh. It is made with green gram eaten as a snack or a breakfast meal.
Drain the dal mixture and grind coarsely. Mix in the chillies, salt, coriander and onions and enough batter to make a dropping consistency.
Proceed to make like dosas--heat tawa or griddle, splash some water over it and immediately pour some batter and spread out. When edges start to rise, put oil all around and a little bit on top. Will come off clean when cooked.
Serve with coconut chutney.
