- Cook the dal: Wash ½ cup toor dal and pressure cook with 1½ cups water and turmeric for about 3–4 whistles. Mash it well.
- Cook vegetables: In a pot, add vegetables, onion, tomato, green chilli, salt and water. Cook until the vegetables are soft.
- Add sambar powder and mix well. Cook for 2–3 minutes.
- Add the mashed dal and mix. Add water to get your preferred consistency.
- Add tamarind water/paste and simmer for 8–10 minutes.
- Temper: Heat oil, add mustard seeds. When they splutter, add cumin, dry red chilli, curry leaves and hing.
- Pour the tempering into the sambar and add fresh coriander.
- Simmer for another 2 minutes and switch off.

🌟 Tip for restaurant-style taste: Add a small piece of jaggery (about ½ tsp) at the end. It balances the sourness and gives that lovely South Indian sambar taste.
