Instructions
Grind one green chili, 1 tsp cumin seeds, ½ tsp whole peppercorns, three garlic cloves, 1 tsp rasam powder or sambar powder, 10 curry leaves, and 2 tsp cilantro stems or leaves into a coarse paste.
Heat a saucepan or kadai and add ½ tbsp oil. When it is hot, temper ½ tsp mustard seeds, ½ tsp cumin seeds, and a pinch of asafoetida.
Add one finely chopped tomato and sauté it for a minute.
Then add 2 cups of water mixed with 1.5 tsp of tamarind paste, or use tamarind juice extracted from a gooseberry-sized piece soaked in 2 cups of water. Add 1.5 tsp of salt and a pinch of turmeric powder, and simmer for 5-7 minutes.
Add the ground paste and cook until the raw smell of the garlic and spices dissipates, about 8 to 10 minutes over medium-low heat.
Then add 2 cups of thin coconut milk, bring to a very gentle boil, and when it becomes frothy on top, turn off the heat.
Finally, garnish with cilantro and serve.

Notes
Feel free to adjust the salt and spices to suit your taste preferences.
You can substitute sambar powder for rasam powder, or even leave it out entirely—just increase the cumin seeds and peppercorns by about ½ teaspoon for added depth.
If you're making this rasam in a pathiyam (light, healing) style, you can skip the green chili altogether.
For tempering, avoid using vegetable or olive oil, as they tend to overpower the delicate flavors. Stick to coconut oil, peanut oil, or any neutral-flavored oil for the best results.
