Method

1. 01

   Pressure cook the lentils.

   Combine the rinsed toor dal, 2 1/2 cups of water, turmeric, and 1 teaspoon of neutral oil in an electric pressure cooker, sealing the lid and cooking on high pressure for 12 minutes. Allow a 10-minute natural release, manually vent the rest, then whisk the cooked dal vigorously until it resembles a smooth, creamy soup.

2. 02

   Sauté the radish to kill the raw smell.

   While the dal cooks, heat 1 tablespoon of oil in a large Dutch oven over medium heat, sweating the chopped onion for 3 minutes before adding the radish rounds. Sauté the radish continuously for 3 full minutes; this direct heat destroys its pungent sulfur aroma and unlocks a deep, sweet flavor.

3. 03

   Bloom the spices.

   Lower the heat slightly and stir in the chopped tomatoes, sambar powder, red chili powder, and salt, allowing the spices to toast against the bottom of the pan for about 30 seconds until highly fragrant.

4. 04

   Simmer the vegetables until tender.

   Pour in 2 cups of water, scraping up any browned bits from the pot, and bring to a gentle boil. Cover and cook for 8 to 10 minutes until the radish slices are completely fork-tender, being careful not to add the tamarind yet as the acid will harden the uncooked root vegetables.

5. 05

   Marry the broth and the dal.

   Once the radish is soft, stir in the tamarind paste and brown sugar, boiling uncovered for 3 minutes to cook off the raw, sharp edge of the tamarind. Pour in the cooked, mashed toor dal, stirring well, and let the stew simmer gently on low heat while you prepare the tempering.

6. 06

   Execute the tempering, or thalippu.

   In a small skillet, heat the ghee over medium-high heat until shimmering, then add the mustard seeds. The moment they pop, immediately drop the heat to low and add the fenugreek seeds, urad dal, and dried chilies, sautéing for 10 seconds until golden. Instantly kill the heat, stir in the asafoetida and torn curry leaves, and step back as you pour the violently sizzling mixture directly into the simmering pot of sambar.

7. 07

   Garnish and serve.

   Stir the sambar thoroughly, taste for salt, and fold in the fresh chopped cilantro. Turn off the heat and let it rest for 5 minutes before ladling it generously over a mountain of steaming white rice.

Notes

• Respect the acid rule.

  Never add tamarind or any acidic liquid to a stew before your root vegetables are fully cooked. Acid strengthens the pectin in plant cell walls, which means your daikon will remain tough and unyielding no matter how long you boil it afterward.

• Watch the fenugreek closely.

  Fenugreek seeds provide a distinct, maple-like bitterness crucial to authentic sambar, but they cross the line from toasty to ruined in seconds. If they turn dark brown or black during the tempering stage, throw the oil out and start over, or they will render the entire pot inedible.

• Radish substitutions are perfectly fine.

  If you cannot source a white daikon radish, standard red salad radishes work beautifully. Just trim and halve them; they don't even need peeling and carry a surprisingly sweet flavor when cooked this way.
