I’ve never really liked tomatoes, and tomato soup? Not my thing. But one chilly afternoon at my friend’s place, she handed me a bowl of this warm, tangy Tomato Rasam with rice and papad. I wasn’t expecting much… but one spoonful of that tamarind-rich, tempered broth, and I was hooked....

How to make Tomato Rasam -Tangy & Light South Indian Soup

Soak the Tamarind

  1. Step 1

    Place the tamarind in a bowl and pour in warm water. Let it soak for 10–15 minutes until soft. Squeeze out the pulp and strain it to remove seeds and fibers. Set the tamarind extract aside.

Cook the Tomatoes

  1. Step 1

    In a pressure cooker, add the tomatoes with 1 cup of water. Cook for 1–2 whistles, then allow the pressure to release naturally. If not using a pressure cooker, boil the tomatoes in a covered pot for 10–15 minutes until soft.

FAQS

  1. Can I make rasam without a pressure cooker?

    Yes, you can boil the tomatoes in a covered pot for 10–15 minutes until soft.

  2. Is Tomato Rasam good for health?

    Yes! It’s light, easy to digest, and full of ingredients like tamarind, black pepper, and cumin that support digestion and relieve cold symptoms. It’s also low in calories and naturally vegan.

  3. Can I make Tomato Rasam without tamarind?

    Yes. You can use lemon juice or a little tomato paste as a substitute, but the flavour will be slightly different.

  4. Can I skip the garlic in this recipe?

    Of course! Garlic adds flavour, but the rasam tastes great without it too.

  5. Can I make Tomato Rasam ahead of time?

    Yes, it keeps well in the fridge for up to 2 days. Just reheat before serving — the flavours deepen over time.
