Coconut Milk Rasam

Step by StepJump to Recipe

Rasams are mostly thin, soup-like dishes that are very popular in all of South India. Most of the rasam varieties are also beneficial for the health as they are good for curing stubborn colds and coughs. On this post, I have shared one of my favorite rasam recipes, the Thengai Paal Rasam a.k.a Coconut Milk Rasam, a specialty from Tamil Nadu. Made with thick coconut milk, tamarind extract, rasam powder and spices, this one is also a vegan recipe.

About Coconut Milk Rasam

In the heart of Tamil Nadu’s culinary repertoire lies a treasure trove of flavors, and among them, Thengai Paal Rasam shines like a pearl in a sea of spices.

Imagine a symphony of aromas wafting from the kitchen, where the comforting scent of coconut melds harmoniously with the zing of tamarind and the warmth of traditional spices.

Also known as Coconut Milk Rasam, this rasam variety is a delightful and fragrant dish from the cuisine of Tamil Nadu in South India.

This unique rasam variation is cherished for its creamy texture, subtle coconut flavor, and a perfect blend of tanginess and spiciness.

Rasam is one of those recipes I often make at home as it is easy and quick to make. Like I said, there are many varieties of rasam made in South Indian cuisine and this Thengai Paal Rasam is one such delicious variety.

The flavor of this Coconut Milk Rasam is different than the usual regular Rasam or Tomato Rasam, as the addition of coconut milk gives a subtle sweet, creamy hint. But it does have a sour taste as tamarind is used.

In fact, the creaminess and sweetness of coconut milk complements the acidity and sourness of tamarind very well. There is also some heat and pungency which comes from the addition of rasam powder.

In this Thengai Paal Rasam, I have used Homemade Rasam Powder. You can use any good quality rasam powder.

Since this spice blend is added, the time does reduce in the overall preparation. I have not added tomatoes. But if you want, you can add 1 small to medium tomato that is crushed or chopped.

Served steaming hot alongside fluffy rice or sipped as a comforting soup, Coconut Milk Rasam is a celebration of the state’s culinary heritage.

Making Coconut Milk Rasam

  • In a pan pour the prepared tamarind extract. Pour 1.5 cups of water.

  • Then turn off the the heat. Add 1 cup thick coconut milk (first extract) and mix very well.
  • Add salt as per taste. Mix, cover pan with lid and set it aside.

Tempering

  • In a small pan or tadka pan, heat 2 tablespoons coconut oil. Instead of coconut oil, you can use any other oil or ghee.
  • Keep the heat to a low and add ½ teaspoon mustard seeds. Let them crackle.
  • Next add 1 to 2 dry red chilies (broken and seeds removed), 1 pinch asafoetida (hing) and 7 to 8 curry leaves.

Notes

  • You can make the rasam with homemade coconut milk or canned coconut milk. 
  • You could also use coconut cream, but adjust water as needed. 
  • The choice of fat for tempering can be coconut oil, gingelly oil (wood pressed sesame oil made from raw sesame seeds) or any other neutral flavored oil. 
  • You can also use ghee instead of oil for a vegetarian variation of this rasam. 
  • I have used dried tamarind. You could opt to use packaged or bottled tamarind paste. Since tamarind paste is concentrated, first add about ½ teaspoon of it and mix with water. If needed you can add more according to taste.
