Rasam

A thin, sour, peppery broth. Never let it boil once the tamarind and dal water are in — it goes cloudy and dull.

    • black peppercorns 1 tbsp
    • cumin seeds 1 tbsp
    • garlic 3 cloves

    Crushed, not ground. You want visible flecks and a rougher heat.

    • from 2 Crush coarsely
    • tomatoes 2
    • rasam powder (optional) 1 tbsp

    • cooked toor dal water 2 cups
  5. Fry until the mustard seeds pop

    2m
    • ghee or oil 2 tbsp
    • mustard seeds 1 tsp
    • dried red chilli 1
    • curry leaves a sprig

    2m
    • from 4 Simmer gently 10 minutes — never boil
    • from 5 Fry until the mustard seeds pop
    • coriander leaves a handful

    The moment it froths up at the edges, it is done. Boiling flattens it.

Do not boil it

Rasam’s character comes from volatile aromatics — pepper, cumin, curry leaf, coriander — which evaporate readily. A rolling boil drives them off and leaves you with sour, salty water. Bring it just to the point where it froths at the edges and take it off. This is also why the tempering goes in last.

Notes

  • Crush the pepper and cumin coarsely rather than grinding fine. Rasam should have texture in its heat.
  • The starchy water from cooking dal is the traditional body. Plain water works and is thinner.
  • Drink it from a cup, spoon it over rice, or use it to clear a cold. All three are correct.

Try butter, 30 minutes, braise, or an ingredient you need to use up.
