Akkaravadisal is a popular Iyengar sweet.You must have tasted it in a lot of vaishnav temples as prasadam.It is similar to sarkarai pongal except that it is cooked in water for sarkarai pongal whereas the Rice and Dal are cooked in milk for Akkaravadisal.In the original recipe, it is sweetened with Jaggery while I have used Sugar. You can use either one.
