Chop okra / vendakkai pieces and fry them for a few minutes in oil to reduce the sliminess. Alternatively I have microwaved the okra pieces for around 6 minutes to reduce oil consumption.
Heat 2 tbsp oil in a pan and add mustard seeds.
Once the mustard seeds crackle, add chana da, urad dal & cumin seeds and saute till the dals are browned.
Now add chopped shallots and curry leaves. Saute for a few minutes.
After the onions are browned, add chopped tomatoes.
Cook the tomatoes till oil separates.
Now add the spice powders including salt, turmeric powder, red chilli powder and coriander powder and saute till the raw smell of masala powders ward off.
Add tamarind pulp or tamarind water. Add water according to your preferred consistency of the curry.
Add sugar / jaggery.
Bring the mixture to a boil and simmer for a few minutes.
Now add the fried okra pieces and cook for around 7 to 8 minutes in a low flame.
Garnish with coriander leaves.
Serve with steamed rice or roti !!
