Add the chopped Basale leaves, chopped tomato and 2 tablespoon chopped onion to a pressure cooker. Add 1 cup water and pressure cook it up to 3 – 4 whistles or till it is cooked. Let the pressure get released naturally.
Meanwhile, heat a kadai and add 2 tablespoon oil.
When oil gets heated, add remaining chopped onion and fry till it turns pinkish.
Add garlic and fry till the raw smell of garlic goes away.
Add the spices – red chilies, cloves, peppercorns and coriander seeds and fry for 2 minutes.
Next add grated coconut and fry till the grated coconut turns brownish.
Switch off the gas and let this cool down.
After cooling, add the grated coconut and onion mixture from kadai to a grinder. Add tamarind and ½ cup water and grind to a thin gravy.
Now the gravy is ready.
The kadai will be empty. Use the same kadai and pour the gravy in it.
Simmer for 2 minutes and then pour the pressure-cooked vegetables in the kadai along with some water.
Add grated jaggery and salt to taste and simmer for 10 minutes.
