We ordered a Thai ( combo) meal at The Sterling resort in Kumbakonam, South India and it is a custom to place a basket of Rice Vadagam (crips) and appalams ( South-indian papad) before the main course arrives...
This yummy crips is made from a batter of rice flour mixed with seasonings and sun dried for about 2-3 days. Then these are fried in oil and accompanied with Thali meals or had as a snack.
