A fragrant South Indian tamarind broth infused with roasted fenugreek and toor dal paste, finished with a sizzling tempered spice garnish. Tangy, lightly bitter, and warming, it is traditionally served with steamed rice.
Warm 8.8 g ghee in a deep, heavy frying pan over medium heat. Tip in the paste spices alongside 8.6 g toor dal and cook for roughly 1 minute, stirring continuously, until the dal becomes golden. Transfer to a small bowl, pour in 125 ml water, and leave to soak for 30 minutes.
Drain the soaked dal and fenugreek mixture, place in a small blender, and blitz to a fine paste.
In the same frying pan, combine 264 g tamarind extract, 1 teaspoon rasam podi, the broth spices, and salt to taste. Place over medium heat and bring to a rolling boil. Lower the heat and let it gently simmer for about 10 minutes, allowing the raw tamarind aroma to cook off.
Add 120 g tomato, the pureed spice paste, and 250 ml water. Simmer gently for approximately 5 minutes until a layer of froth rises to the surface, then remove the pan from the heat.
Heat 8.8 g ghee in a small frying pan set over medium heat. Toss in the tempering spices along with 1 g curry leaf and cook for roughly 1 minute until the mustard seeds begin to crackle.
Pour the hot tempering mixture straight into the rasam. Stir to combine, garnish with 2 g coriander leaf, and serve with plain boiled rice.
Use 40% to 50% of the fresh tomato weight mixed with a splash of water. Imparts a deeper red colour, thicker sauce, and slightly sweeter cooked flavour.
Use 120% of the weight; melt gently over low heat to avoid burning the milk solids, which will yield a softer, creamier richness rather than a nutty aroma.
Use the same weight. The seeds are smaller and hotter; fry in hot oil until they pop, about 20–30 seconds, and reduce the heat if they darken too fast. The dish will be a little sharper.
Use 70% of the weight of whole seed, added with the other ground spices rather than fried whole. You lose the popping texture and the heat comes through more evenly.
