Step 1: Prepare Rasam Powder

In a mortar and pestle, coarsely crush black peppercorns, cumin seeds, garlic cloves, and red chili until aromatic.

Step 2: Cook Tomatoes

In a saucepan, add chopped tomatoes, turmeric powder, and 1 cup of water. Cook on medium heat for 5-6 minutes until tomatoes turn soft and mushy.

Step 3: Extract Tamarind Juice

Squeeze the soaked tamarind in water to extract juice. Strain and add to the cooked tomatoes.

Step 4: Add Spices and Simmer

Add the prepared rasam powder, salt, and remaining water to the pan. Mix well and simmer on low heat for 8-10 minutes until the rasam becomes aromatic and frothy (do not boil vigorously).

Step 5: Prepare Tempering

In a small pan, heat oil or ghee. Add mustard seeds and let them splutter (about 30 seconds). Add curry leaves and asafoetida, sauté for 10 seconds until fragrant.

Step 6: Finish Rasam

Pour the tempering over the simmered rasam. Add chopped coriander leaves, mix, and turn off the heat. Serve hot with rice or as a soup.

• Use ripe tomatoes for the best flavor and color.

• Do not boil rasam for too long after adding coriander leaves to preserve the fresh aroma.

• Adjust the amount of black pepper and chili to suit your spice preference.

• Add a small piece of jaggery for a hint of sweetness.

• Include cooked toor dal for a thicker, protein-rich rasam.
