Rinse and Cook the Dals: Combine the mung beans and masoor dal in a bowl. Wash them under running water, swirling with your fingers, until the water runs clear.

Drain well.

Place the rinsed dals in a heavy-based pot with 4½ cups of water.

Bring to a rolling boil, using a spoon to skim off any foam that rises to the surface.

Simmer to Perfection: Stir in the ground turmeric, chopped green chilies, and the crushed garlic clove.

Reduce the heat to low, partially cover the pot, and let it simmer very gently for about 45 minutes, or until the dals are completely soft and tender.

Finish the Dal Base: Once cooked, use a potato masher or an immersion blender to gently mash the dal to your desired consistency—I like it mostly smooth with a little texture.

Stir in the salt.

Prepare the Tarka: While the dal is finishing, heat the oil in a small frying pan or tadka pan over medium-high heat.

When the oil shimmers, add the cumin seeds.

Let them sizzle and become fragrant for about 5 seconds.

Bloom the Spices: Add the dried red chili and stir for a few seconds until it darkens slightly. Immediately add the slivered shallots and fry, stirring frequently, until they turn a deep, reddish-brown and become crispy.

Combine and Serve: Carefully pour the entire sizzling tarka—oil and all—directly over the cooked dal. Immediately cover the pot with a lid for a minute to trap all the incredible aromas.

Stir gently just before serving hot.

Adjust the final consistency by adding a splash of hot water if the dal is too thick, or simmering it uncovered for a few more minutes if it's too thin.

Don't rush the shallots!

Frying them to a deep reddish-brown is key to developing a rich, sweet, and savory flavor in the tarka.
