Donot throw away the cooked water — it forms the base of the rasam. - prep
Prepare the tamarind water.
Soak tightly packed tamarind in 1/4 cup warm water for 10 minutes. Squeeze well to extract the pulp and discard the fibers. Set the tamarind water aside.

Crush the spice paste.
Using a mortar and pestle, lightly crush the garlic cloves with skin, cumin seeds, and black peppercorns into a coarse paste. Set aside.
TIPKeeping the skin on garlic adds a rustic aroma. Pounding instead of grinding releases essential oils without turning it into a fine paste. - simmer · ~10 min

What to keep in mind.
7 tips from the recipe — small details that make a real difference to the final dish.
- 1Soaking horsegram for at least 2 hours cuts cooking time and ensures even softening.
- 2Reserve the cooked horsegram water — it's the flavorful, nutritious base of the rasam.
- 3Pound garlic with its skin on using a mortar and pestle for a rustic, aromatic paste.
- 4Do not over-boil after adding the tempering; a single rolling boil preserves the fresh fragrance.
- 5Adjust the rasam's consistency with extra water; it should be sippable, not thick like a dal.
- 6Let the rasam rest for 5 minutes off heat before serving to allow flavors to meld.
- 7Serve hot in small bowls or as a soup with rice to balance its peppery kick.
