Pepper Rasam Recipe

Simmer tomatoes

Place chopped tomatoes and 2 cups of the water in a medium saucepan. Bring to a gentle simmer over medium heat and cook until tomatoes are very soft and breaking down, about 8–10 minutes.

Blend and strain

Remove from heat. Let cool slightly (2–3 minutes) then puree the tomato mixture with the remaining 2 cups of water until smooth. Pass the puree through a fine-mesh sieve or chinois into a clean pot or bowl to yield a clear consommé-like liquid, pressing solids lightly. Discard solids left in the sieve.

Add tamarind concentrate and salt to the strained tomato liquid and warm gently over low heat. Taste and adjust salt and tamarind (for acidity) as needed. Keep warm but do not boil vigorously.

Crush pepper and cumin

Using a mortar and pestle or spice grinder, coarsely crush the black peppercorns and cumin seeds together. The texture should be mostly coarse with some finer bits—this gives pronounced heat and aroma.

Prepare tempering

Heat ghee or oil in a small skillet over medium heat. When hot, add mustard seeds. When they begin to pop, add the crushed garlic and sauté briefly (30–45 seconds) until fragrant and just turning golden. Add asafoetida, curry leaves and the optional slit green chili; fry for 10–15 seconds until curry leaves sizzle.

Add the crushed pepper-cumin mixture to the hot tempering and stir for 15–20 seconds on low-medium heat to bloom the spices — be careful not to scorch the pepper. Remove the pan from heat immediately once aromatic.

Pour the hot tempering (oil with spices, garlic and curry leaves) into the warm strained tomato-tamarind liquid. Stir gently to combine. Keep the combined rasam at a gentle simmer for 2–3 minutes to let flavors marry; do not boil vigorously to keep the broth clear.

Taste and adjust seasoning: add more crushed black pepper for heat (about 1/2 tsp increments) or more tamarind/lime for tang. Stir in lime or lemon juice, then remove from heat.

Ladle the Pepper Rasam into bowls, garnish with chopped cilantro and serve immediately as a clear, peppery consommé. It can be enjoyed as a soup or served over steamed rice.
