A bengali authentic recipe of bottle gourd filled with mustard seeds and coconut chal kumro—which is ash gourd, called so because they were grown on roofs ("chal" in Bangla)—is stuffed with a pungent mustard and coconut filling, then dipped in a batter and fried. This is served as a side with dal, rice and a torkari (any vegetable dish), before the fish or meat course.
