Equipment

  • 1 Deep wok or pan
  • 1 Grinder or spice blender

Ingredients
  

  • 1 tsp black pepper
  • 2 tsp cumin seeds
  • 3 dried red chilies
  • 1 tbsp sesame oil or any cooking oil
  • 2 tsp mustard seeds
  • 1 tbsp chopped garlic
  • 1 tbsp chopped ginger
  • 10 curry leaves
  • 3 medium tomatoes chopped
  • 1 tbsp tamarind pulp or ½ cup tamarind water
  • ½ tsp turmeric powder
  • Salt to taste
  • 4 cups water
  • ¼ cup cooked toor dal optional, for thicker rasam
  • Fresh coriander leaves for garnish

Instructions
 

  • Heat a deep wok on high flame. Dry roast 1 tsp black pepper and 2 tsp cumin seeds for 2–3 minutes until aromatic.
  • Transfer spices to a plate to cool, then dry roast 2–3 dried red chilies for 1 minute.
  • Grind roasted pepper, cumin, and chilies into a coarse powder – this homemade rasam powder gives authentic flavor.
  • In the same wok, heat 1 tbsp sesame oil. Add 2 tsp mustard seeds and let them splutter.
  • Add 1 tbsp chopped garlic and ginger, sauté 1 minute until golden.
  • Add curry leaves, 2–3 chopped tomatoes, and salt. Cook 2–3 minutes until soft.
  • Stir in 1 tbsp tamarind pulp (or ½ cup tamarind water) and simmer for 2 minutes for the tangy base.
  • Add the ground spice powder and ½ tsp turmeric powder. Mix well.
  • Pour in 3–4 cups water (and cooked toor dal if using). Bring to a boil, then simmer for 10 minutes for a light, soupy tomato rasam with tamarind.
  • Serve hot, garnished with fresh coriander. Enjoy this South Indian rasam soup with rice or sip it warm as a comforting drink.

Notes

  • For extra tang, you can add 1 tablespoon of tamarind pulp during cooking.
  • Garnish South Indian Rasam soup with fresh coriander before serving.
  • Adjust spice level by reducing red chilies if you prefer mild rasam.
