Biharis sure seem to have a sweet tooth. Yes you read that right, they even turned the plain old vegetable like parwal/patol (pointed gourd) into a sweet dish, reverberant of the food of Bihar. And boy, it tastes heavenlly. The inner pulp of the parwal is scooped out, bolied, dipped in syrup and filled with sweet khoya preperation. The end result looks as royal as it tastes!
