Urad dal-2 cups
Green chilly-3 nos
salt to taste
oil for deep fry
u can also add chopped onion,ginger,curry leaves.But I don't added,I like to have the plain vada.soak the urad dal about 2 to 3 hour.drain out the water.
To get a nice fluffy vada ,let the dough rest for 20 to 30 mins.If u r using wet grinder u can make vada immediately.
