Soak the Toor dhal for at least 30 mins
Soak the Tamarind in about 1/2 - 3/4 cup boiling water
Prepare the masala by first frying the onion and garlic and then adding the rest of the masala ingredients
Allow to cool and then puree with a little water
Add some more oil back into the pot and add the green chillies
Cut veggies into fairly uniform pieces and add the potato in first followed by the pumpkin and carrot, beans and the drumstick.
Add all of that ground Sambhar masala
Add the Tomato and the soaked Toor dhal
If you don’t have a pressure cooker, cook the toor dhal separately, till mushy and then puree and add to the veggies.
In total I’m going to add 2-3 cups of water till the veggies are just about covered.
Add salt to taste
Squeeze that tamarind to extract all the juice and add that in as well
Add the Jaggery
Pressure cook mode for 20 mins
Saute all the tadka ingredients and pour it into the Sambhar and serve
