Rasam Recipe

Soak tamarind

Break the tamarind pulp into a small bowl, pour 1 cup hot (not boiling) water over it, let sit 10–15 minutes to soften.

Mash the soaked tamarind with your fingers to extract pulp and juice. Strain the mixture through a fine mesh sieve or cheesecloth into a bowl, pressing solids to get about 3/4 to 1 cup tamarind extract. Discard fibrous solids.

In a medium saucepan, add the chopped tomatoes and 3 cups water. Bring to a gentle boil over medium heat, then reduce to simmer for 8–10 minutes until tomatoes are soft and begin to break down.

Use a potato masher or spoon to lightly crush the tomatoes in the pot, creating a coarse tomato broth. If you prefer a smoother rasam, briefly pulse the cooked tomatoes with an immersion blender (1–2 quick pulses).

Stir the turmeric, sambar/rasam powder, salt, and freshly ground black pepper into the simmering tomato broth. Add the tamarind extract, stir to combine, and simmer gently for 6–8 minutes to let the flavors meld. Taste and adjust salt or pepper as needed.

If using green chili, split and add it while simmering for a mild heat; remove before serving if you want just flavor without extra heat.

In a small skillet over medium heat, warm the oil or ghee. When hot, add mustard seeds and wait until they begin to pop. Add cumin seeds and let them sizzle for a few seconds, then immediately add a pinch of asafoetida and the curry leaves. Fry for 5–8 seconds until fragrant—be careful not to burn the seeds.

Pour the hot tempering immediately into the simmering rasam. Stir once. The sizzle will lift the aromatics into the soup.

Turn off heat and add chopped cilantro and lemon juice (if using). Cover for 1–2 minutes so the cilantro wilts slightly and flavors marry.

Serve rasam hot as a thin soup or over steamed rice. This recipe yields a tangy, peppery rasam — adjust pepper or tamarind to taste for more heat or sourness.
