Colocasia or let us call it by the indian term “arbi” is a starchy but delicious root vegetable in the world of food. It is at most used as a stir fry, dry subzi, in curries which are spiced and/or yogurt based. This recipe is taken from a 1996 femina magazine edition which had featured a contest using tomato puree. The gram flour is roasted well and when combined with mashed colocasia binds it into a very sticky mixture. On frying, it will not disintegrate in the oil giving you perfect balls.
