Plain Dosai (South Indian Crepes)
This is a common South Indian food that uses leftover rice. It can be had for breakfast, lunch, or as a snack. The 12 hours mentioned is just overnight soaking. The process is similar to making crepes or pancakes. You can find urad dal at most Indian grocers. Dosas are best eaten hot out of the pan and are usually served with coconut chutney and sambhar (a South Indian hearty lentil soup).
