Method of Preparation :
Heat oil, add seasonings. When they crackle, add vatral and fry well. Mix in sambhar powder. Pour tamarind extract, salt and boil. For thickening the gravy add a little rice flour mixed in water. Allow to boil till the gravy thickens. Add a little jaggery before removing from fire. Garnish with curry leaves. Instead of vatral fresh vegetables can be used to make this curry. Instead of Sambar powder, red chilli powder (1 tsp), coriander powder (2 tsp) and fenugreek powder (1/2 tsp) can be sautéed in oil and used.
