For this South Indian sambar recipe, add cleaned and washed tur dal, turmeric and 2 cups water to a pressure cooker and pressure cook for 4-5 whistles.
Allow the steam to escape; open the lid and mash the cooked yellow lentils with the back of a ladle. Keep aside.
Wash, peel and cut the vegetables. Add the chopped vegetables and 1 cup of water to the dal, mix well and pressure cook for just one whistle.
Open the lid and stir in the sambar masala powder, salt and tamarind paste. Mix in jaggery, simmer the sambar on low heat for 4-5 minutes, while stirring occasionally. Adjust the consistency of the sambar to your liking.
While the sambar is cooking, heat 1 tbsp ghee in a pan over medium flame. Add mustard and cumin seeds. Once they start to splutter, add dry red chillies, asafoetida and curry leaves. Sauté for 10-15 seconds.
Pour the prepared tempering over the cooked dal. Bring to aboil and let it simmer for a couple of minutes till all the sambar ingredients are well incorporated. Garnish with finely chopped coriander leaves.
Serve piping hot Toor Dal Sambar South Indian style with idli, vada, dosa or steamed rice.
