Method

  1. Submerge 4.3 g toor dal and the paste spices in 250 ml warm water for 30 minutes.
  2. Drain the soaked dal and spices, process in a small blender until completely smooth, then whisk in 250 ml water to dilute the mixture and set aside.
  3. In a heavy pot, combine 396 g tamarind extract, 0.75 tsp rasam podi, and salt to taste. Bring to a boil, then lower the heat and simmer gently for 10 minutes until the sharp raw tamarind smell dissipates.
  4. Pour the diluted paste into the saucepan, loosening with an extra splash of water if too dense, and return to a boil. Turn down the heat and simmer for 5 minutes until a light foam rises across the surface.
  5. Warm 8.8 g ghee in a small skillet over medium heat. Tip in the tempering spices along with 1 g curry leaf and sizzle for about 1 minute until the seeds crackle, then immediately stir the hot spiced fat into the rasam.

Don't have something?

Tamarind extract
  • Tamarind

    Use 180% of the weight of compressed tamarind; soak in three times its weight of boiling water for 15 minutes, knead, and strain out the thick pulp.

  • Dried mango powder

    Use 35% of the weight dissolved in two tablespoons of warm water. Provides sharp tang, though the resulting sauce will be lighter in colour.

  • Lemon juice

    Use equal weight, added right at the end of cooking. Adds sharp acidity without the deep brown hue or pulpy thickness.

Pepper water spice mixture
  • Lentil stew spice mix

    Use 60–75% of the weight; it is similar but more complex, so adjust salt, tamarind and heat.

  • Chettinad sambhar powder

    Use 50–60% of the weight; it is hotter and more aromatic, so taste before adding more.

  • Lentil stew spice mix

    Use 60–75% of the weight; it gives a rounded spice base but less pepper-forward heat.

Toor dal
  • Red lentils

    Use equal weight. Cooks considerably faster and breaks down into a softer, creamier consistency with an earthier taste.

  • Chana dal

    Use equal weight. Requires longer soaking and cooking; remains firmer with a nuttier bite and less starchy thickening.

  • Split mung beans

    Use equal weight. Cooks quickly to a lighter, more delicate, and silky texture.

Cumin seed
  • Ground cumin

    Use 70% of the weight; add with ground spices or sauce bases rather than hot oil tempering, where it scorches quickly and turns bitter.

  • Black cumin seeds

    Use equal weight for oil tempering. Delivers an earthy profile with an additional musky, smoky, and slightly bitter edge.

  • Fennel seed

    Use 60% of the weight for tempering; offers comparable warm aroma, but leans sweet and liquorice-like rather than savoury and earthy.

Ghee
  • Unsalted butter

    Use 120% of the weight; melt gently over low heat to avoid burning the milk solids, which will yield a softer, creamier richness rather than a nutty aroma.

  • Vegetable oil

    Use 85% of the weight; holds high cooking temperatures without smoking, but the final dish will lack traditional dairy depth.

  • Mustard oil

    Use equal weight; heat to smoking point and cool slightly before cooking, bearing in mind it introduces an assertive, pungent edge.

Mustard seed
  • Black mustard seed

    Use the same weight. The seeds are smaller and hotter; fry in hot oil until they pop, about 20–30 seconds, and reduce the heat if they darken too fast. The dish will be a little sharper.

  • Yellow mustard seeds

    Use the same weight. They are milder and larger; fry a few seconds longer until they pop. The finished dish will have less pungency.

  • Ground mustard seed

    Use 70% of the weight of whole seed, added with the other ground spices rather than fried whole. You lose the popping texture and the heat comes through more evenly.

Dried red chilli
  • Dried kashmiri chilli

    Use equal weight whole. Fry in hot oil or ghee as tempered spice; gives a richer red colour with slightly milder heat.

  • Red chilli powder

    Use 50% to 70% of the weight. Stir into the oil with ground spices; distributes heat evenly throughout the dish without whole chilli skins.

Curry leaf
  • Bay leaf

    Fry 1 bay leaf for every 5 curry leaves in hot oil; imparts a warm, woodsy background note, but misses the citrus-sulphury punch entirely.

  • Lime juice

    Add a small squeeze (about 5 ml per sprig of curry leaves) right before serving; provides sharp citrus top notes without the toasty, herbal aroma.
