Steps
- 1
Rinse the toor dal in several changes of water until the water runs mostly clear.
- 2
Put the dal in a pot with 1 1/2 cups water, bring to a boil, then cover and simmer for about 25 minutes until completely soft (or pressure cook for 3 whistles).
- 3
While the dal cooks, soak the tamarind in 1 cup hot water for 10 minutes.
- 4
Squeeze the softened tamarind with your fingers, then strain the liquid and discard the fibres.
- 5
Coarsely crush the peppercorns, cumin seeds, coriander seeds and garlic together using a mortar and pestle.
- 6
Mash the cooked dal with its water until smooth and set aside.
- 7
In a saucepan, combine the tamarind water, chopped tomatoes, turmeric, salt and the crushed spice-garlic mix.
- 8
Simmer for about 10 minutes, until the tomatoes break down and the raw tamarind smell fades.
- 9
Stir in the mashed dal and the 2 cups of extra water.
- 10
Heat gently until the rasam turns frothy on top, about 3 to 4 minutes, then turn off the heat without letting it boil hard.
- 11
In a small pan, heat the oil and add the mustard seeds; let them pop.
- 12
Add the dried chillies, curry leaves and asafoetida, and sizzle for a few seconds.
- 13
Pour the tempering over the rasam and stir.
- 14
Scatter over the chopped coriander leaves, then taste and adjust the salt before serving hot.
Swaps, storage and make-ahead
Swaps
- For a gluten-free rasam, use an asafoetida labelled gluten-free, since many brands are blended with wheat flour, or simply leave it out.
- If you can't find toor dal, use the same amount of split red lentils (masoor dal), which cook faster and mash just as smoothly.
- Swap the tamarind block for about 1 tsp of tamarind concentrate stirred into the hot water, or use the juice of half a lemon added at the end.
- If fresh curry leaves are hard to find, leave them out and add a little extra fresh coriander when serving.
Storage
Cool the rasam and refrigerate it in a covered container within 2 hours, then use it within 3 to 4 days. Reheat gently until steaming hot. The flavour softens over time, so it tastes best fresh.
Make ahead
Cook and mash the dal, strain the tamarind water and crush the spice-garlic mix up to a day ahead, keeping each covered in the fridge. Simmer the rasam and make the tempering just before serving.
