To the pressure cooker, add the dal, tomatoes, ginger, chilis (if using), turmeric, salt and water. Cook until the lentil is completely mushy (mine took about 15 minutes)
Once the pressure settles, open the cooker and whisk the dal throughly. You may add some more water if you want the dal slightly runny and then put it to simmer on a low flame
In a small pan, heat the ghee. Once it melts add the cumin seeds, hing and the dried chili
When aromatic, lace the dal with this tempering. Add in the coriander leaves and mix well. Turn the flame off
Serve this delicious toor dal with tomatoes and ginger with rice and some papad, along with a wedge of lemon. Enjoy!
