Method

  1. Put the lentils, turmeric, and 750 ml (25½ fl oz/3 cups) water in a large saucepan over medium heat. Bring to a boil and cook, uncovered, for about 30 minutes, or until the lentils are soft. (Whole red lentils will take longer to cook than split lentils.)

  2. Meanwhile, to make the sambar paste, grind the yellow split peas using a mortar and pestle or an electric spice grinder. Transfer to a small bowl and mix with the fenugreek, chilli powder, cumin, coriander, coconut, and tamarind pulp to form a paste.

  3. When the lentils are cooked, stir in the sambar paste, eggplant, cauliflower, green beans, and tomato. Cook over medium heat for 15 minutes. Add salt to taste.

  4. About 5 minutes before the sambar is ready, make the tempering. Heat the ghee or butter in a small frying pan over high heat. Add the mustard, cumin, and fenugreek seeds, dried chillies, and curry leaves. Heat until they begin to crackle. Immediately add the onion and sauté, stirring occasionally, for about 5 minutes, or until golden brown.

  5. Pour the tempering over the sambar, garnish with chopped coriander leaves if desired, and serve.
