Ingredients
- 4 medium tomatoes, fresh
- 3 cups water
- ½ teaspoon mustard seeds
- 2 whole dried red chiles (whole or broken)
- ½ teaspoon ground cumin
- ½ teaspoon salt
- ¼ cup fresh cilantro, chopped
Instructions
- 1
Cut each tomato in half horizontally (through the middle, not from top to bottom), then cut each half into quarters. Place all tomato pieces in a medium pot.
- 2
Pour 3 cups of water into the pot with the tomatoes and stir once to mix.
- 3
Place the pot over medium-high heat and bring to a boil, watching until you see large bubbles breaking the surface continuously, about 5–7 minutes.
- 4
Reduce heat to medium-low and simmer for 8 minutes, stirring once halfway through, until the tomato pieces are completely soft and starting to break apart.
- 5
Use a wooden spoon to press the tomato pieces against the side of the pot, breaking them into a pulpy liquid. Strain the mixture through a fine-mesh sieve into a clean pot, pressing the solids to extract all liquid, then discard the solids.
- 6
Return the strained liquid to medium heat and add 0.5 teaspoon mustard seeds and 2 whole dried red chiles. Stir constantly for 30 seconds until the mustard seeds begin to pop and crackle loudly.
- 7
Add 0.5 teaspoon ground cumin and stir for 20 seconds until the spice smells fragrant and warm.
- 8
Add 0.5 teaspoon salt and stir to combine thoroughly.
- 9
Simmer gently for 2 minutes without stirring, then remove from heat.
- 10
Ladle the rasam into two bowls and scatter fresh cilantro on top of each serving.
