Chop the tomato, garlic, and dry red chilies separately. You can use a chopper or chop them by hand. Set aside a small portion of chopped coriander leaves for garnishing.

Soak half of a medium-sized lemon of tamarind in warm water and extract a thick tamarind juice. Set it aside.

Heat 1-2 teaspoons of oil in a pan.
- Add a small pinch of mustard seeds and let them splutter.
- Add a small pinch of cumin seeds and sauté them separately to experience different aromas.
- Add dry red chilies and curry leaves. Let them splutter.
- Add the chopped tomato and garlic. Sauté for a few minutes until the tomatoes soften.

While sautéing, add a small pinch of turmeric powder and mix.
Add salt to taste and continue sautéing for about 2 minutes.

When the tomatoes are soft, add the tamarind extract in a thick consistency.
Mix the tamarind extract well with the mixture.

Let the mixture simmer until the raw smell of tamarind disappears.

Once the raw smell is gone, add 1/2 tsp of cumin powder, 3/4 to 1 tsp of black pepper powder, and a pinch of asafoetida. Stir well. Be careful not to let the rasam boil after adding these spices, as it may affect the taste.

Finally, add the remaining chopped coriander leaves.
Reduce the flame to low. When the rasam begins to simmer from the sides, turn off the heat.

Garnish with a few fresh coriander leaves.

Serve your delicious Thakkali Milagu Rasam hot with steamed rice. It can also be served as a comforting soup.
