Lemon Rasam is a South Indian soup made with dal, tomato and lots of lemon. Freshly made spice paste gives this brothy soup a nice kick and lots of flavor.

Rasam is a quintessential side dish to most South Indian meals. It is a brothy soup that is typically made with dal (lentils). In many households, rasam podi or the spice powder is made fresh and that adds lots of flavor to the dish.
Nimmakaya Charu | Lemon Rasam:
Today's rasam is made with tangy lemon juice and freshly ground spice paste. There are just 3 ingredients in the spice powder:
- Cumin seeds
- Peppercorn
- Green Chilies
The ingredients are ground to a coarse texture and added to the charu/ rasam while boiling.
Difference between Andhra Rasam and Tamil Rasam:
Rasam in Andhra is called charu/ chaaru. It is generally made with tomato and tamarind. Dal is usually not added to rasam which makes it very brothy and is usually eaten along with a thicker dal.
But this Tamil Nadu version of rasam uses a little bit of dal for thickening. A freshly ground spice powder along with sambar powder is used to flavor the rasam. This gives a nice spicy taste to the dish.
Lemon juice is added to make the dish tangy instead of tamarind. It is a very comforting and yummy dish that is perfect to serve with any South Indian meal.
Other Ingredients needed:
Toor dal is added to the rasam to make it thick and add protein. Finely chopped or pureed tomatoes are also added for tanginess and freshness. Lemon juice is the key ingredient that is highlighted by the spice paste.
This lemon rasam Recipe is adapted from Nalini's blog. This is a comforting dish that reminds of home and mom's cooking. The rasam itself will warm you inside out and will tickle the taste buds. Serve with steamed rice and a vegetable curry for a filling and delicious meal.
