Tarka Dal

Ingredients

• 9 oz chana dal
• 900 ml water
• 3 tbsp vegetable oil
• 1 tbsp cumin seeds
• 1 onion
• 4-6 green chillies
• 1 fresh ginger
• 3 garlic cloves
• 3 tomatoes
• 3/4 tsp ground turmeric
• 3/4 tsp garam masala
• 1.5 tsp ground coriander
• fresh cilantro
• 100 ml water
• black pepper

Method

Tarka dal is built on two parallel operations that converge at the end: a slow cook of lentils that breaks down into creamy submission, and a spice-infused oil base that carries heat and flavour. Start both simultaneously.

Rinse the chana dal under cold water, then place it in a heavy pan with 900 ml of cold water. Bring to a rolling boil uncovered. Skim the grey foam that rises in the first two minutes — this is denatured protein and will muddy the broth if left. Once clean, reduce to a steady simmer, cover, and stir every 8–10 minutes. The dal is ready when each grain collapses under gentle pressure, roughly 35–40 minutes. Top up with boiling water only if the level drops below the surface of the lentils; too much water leaves a thin soup. Set aside without draining.

While the dal simmers, build the tarka. Heat the vegetable oil in a separate pan over medium heat until it shimmers — roughly 30 seconds. Add the cumin seeds and listen for a sharp crackle; this takes 15–20 seconds and releases the seed's essential oils into the fat. Immediately add the diced onion, sliced green chillies, and grated ginger. Cook without stirring for the first minute to build colour on the onion's cut faces, then stir every 30 seconds until the mix is golden and soft, around 4–5 minutes. Blend the garlic and tomatoes to a smooth paste — this accelerates their breakdown and ensures even distribution — then add to the pan. Stir constantly for 90 seconds so the paste loses its raw edge. Add the turmeric, garam masala, and ground coriander and cook for another minute; the spices will darken slightly as they toast in the oil.

Pour in the 100 ml of water and bring to a gentle simmer. The sauce will tighten and darken over the next 15–20 minutes as the water reduces and the tomato's acidity cooks away. The oil will separate and pool on the surface — this is your signal that the aromatics have given everything they have. Season with salt now, tasting as you go.

Whisk the cooked dal vigorously until it breaks down into a loose purée — this thickens the dish and creates the signature creamy texture. Stir the tarka into the dal, adding more hot water if needed to reach a soupy consistency that clings to the back of a spoon. Bring briefly to a boil, taste, and adjust salt. Finish with a generous grind of black pepper and torn cilantro.
