Ingredients to make Onion Rasam

  • tamarind – 1 small lemon size
  • ghee – 2 tsp
  • mustard – 1/2 tsp
  • Dry Red Chili - 1

How to make Onion Rasam

  1. To begin making the onion rasam, peel shallots/small onions and chop them finely. Reserve 1 tsp of chopped onions for garnishing at the end.
  2. Prepare the tamarind extract by adding 200ml water to tamarind and diluting it.
  3. The rasam cooking process starts with tempering first, so take a stainless steel bowl and add 2 tsp of ghee to it. Once the ghee is melted, add mustard seeds and as they splutter, add dry red chili and carom seeds in low flame.
  4. Once the carom seeds are fried, add the sliced onion and sauté till the onions are caramelized. The onion flavor would be infused into the tempering once they are caramelized.
  5. Add mint leaves and sauté for a minute.
  6. While the tempering in done, continue to making the recipe by adding the tamarind extract, salt to it. Bring to a boil and cook on high flame for 3 minutes and medium flame for 7 minutes or till the raw smell of tamarind disappears.
  7. Add the rasam powder, remaining water and continue to cook in medium flame until rasam becomes frothy at the top.
  8. Switch off immediately, add the reserved 1 tsp finely chopped small onions and close with a lid. The addition of onions provides a crunch while consuming the rasam. Allow the raw onions to infuse for at least 30 minutes.
  9. Serve with hot rice.
