Prep Time10 mins
Cook Time30 mins
Course: Main Course, Mains
Cuisine: Indian- South, South Indian, South Indian Tambrahm
Servings: 3


2 tablespoon Toor dal

  • ¾ c water
  • ½ teaspoon turmeric powder
  • 3 Green chilies slit lengthwise
  • ½ cup finely chopped Tomato
  • 2 teaspoon grated ginger
  • 3 tablespoon freshly squeezed lemon juice
  • 1.25 teaspoon Salt or to taste


  • 1 teaspoon ghee or oil
  • 1 teaspoon mustard seeds
  • 1 teaspoon cumin seeds
  • 1 teaspoon crushed black pepper


  • 1 tablespoon finely chopped Coriander leaves


Cooking toor dal

  • Pressure cook the toor dal along with 1 green chili, 2 cups of water and turmeric until mushy.
  • Once done, drain the water completely and preserve.
  • Mash the dal well.
  • To the reserved water, add the green chili, turmeric powder, hing, grated ginger,  tomato and salt.
  • Allow this to simmer on low flame for 2 to 3 minutes.
  • Add the mashed dal and mix well.


  • After adding the dal, let the mixture simmer until frothy at the surface.
  • When done, allow the Rasam to cool down a bit.


  • Once cool, heat ghee in a pan and pop the mustard.
  • Add the cumin seeds and crushed black pepper now and wait for it to crackle.
  • As soon as the spices crackle, our tempering is ready.
  • Add the tempering to the prepared rasam.


  • Finally, squeeze the juice of the lemons into the rasam and mix well.
  • Garnish with coriander leaves and curry leaves.


If you add the lemon juice before the rasam cools down, it will turn bitter. 
You can skip the ghee and temper with oil for a vegan version. 
If you dont like the after taste of pepper, you can skip that too and let the green chili flavor shine through.
Never reheat this rasam. It will become bitter since we add lemon juice.
