Ingredients
Instructions
- Rinse the lentils in a fine-mesh sieve under cold running water until the water runs mostly clear.
- Cook the vegetable base: In a large stockpot, heat the oil over medium heat until shimmering. Add the onions and celery with a pinch of salt. Sauté for 12–18 minutes, stirring occasionally, until the vegetables are well softened and turning golden.
- Add the carrots to the pot and cook for 3–5 minutes until they begin to soften.
- Stir in the aromatics: Process the garlic and ginger in the chopper attachment for the hand-blender until finely ground, then add them to the pot. Cook for 1–2 minutes until intensely fragrant.
- Bloom the ground spices: Add the ground cumin, turmeric, coriander, chili flakes, and black pepper. Stir for 30–45 seconds until the spices are toasted and fragrant.
- Simmer the soup: Stir in both types of lentils, the water, and the salt. Bring the mixture to a boil, then reduce the heat to maintain a steady simmer. Cook for 35–45 minutes, stirring occasionally, until all lentils are completely tender. Add more water if needed to reach your preferred soup consistency.
- Thicken the texture: Using a potato masher or a brief pulse with an immersion blender, mash about 20% of the lentils to create a creamy but textured consistency.
- Finish the pot: Turn off the heat and stir in the garam masala. Taste and adjust with additional salt as needed to reach a perfect balance of earthiness and depth.
Mustard-Cumin-Garlic Tadka
- Heat the oil in a small skillet over medium heat until shimmering and hot.
- Bloom the seeds: Add the mustard seeds first. When they begin to pop and crackle, immediately add the cumin seeds and coriander seeds. Fry for 10–15 seconds until fragrant and sizzling.
- Sauté the garlic: Add the thinly sliced garlic. Fry for 1–2 minutes, stirring constantly, until the garlic is pale golden and crisp.
- Final aromatics: Add the fenugreek seeds (if using) and fry for only 5–10 seconds until you smell a nutty aroma and to avoid bitterness.
- Stir in the chili: Remove from heat and stir in the remaining red chili flakes. The oil should be a deep vibrant red.
- Combine: Immediately pour the sizzling hot tadka over the soup pot. Stir gently to incorporate, or reserve some to drizzle over individual bowls.
Plating & Garnishing
- Serve the dal in warm bowls, ensuring each serving gets a bit of the golden garlic tadka.
- Garnish with a fresh lemon wedge on the side for squeezing just before eating.
- Finish with a few grinds of black pepper for extra heat.
Storage & Leftovers
- Cooling: Portion the large batch into shallow containers to ensure it cools within 2 hours.
- Refrigeration: The soup keeps for up to 4 days. It will thicken significantly as it sits; add a splash of water or stock when reheating to restore the soup-like consistency.
- Freezing: Transfer to freezer-safe containers (leaving headspace) and freeze for up to 3 months. Thaw overnight in the fridge before reheating.
- Refresh: A fresh squeeze of lemon after reheating will brighten the flavors and make it taste like day one.
