Step 1

Make the Sakahar barha masala: Heat a non-stick frying pan. Add all the whole spices and dry roast over a medium heat until they colour, puff up and start releasing their aroma. Transfer to a plate and leave to cool. Using a spice grinder or coffee grinder, grind the toasted and cooled whole spices in batches until finely powdered. Mix in the ground spices until well blended. Transfer to a screw top jar or other airtight container. For best results, use any leftover spice mix within two weeks.

Step 2

Wash the chana dal under running water and soak them for 30–60 minutes in lukewarm water.

Step 3

In a medium heavy-based saucepan, combine the drained chana dal, turmeric, fresh green chillies, whole spices and salt. Cover with 1.4 litres of water and bring to the boil.

Step 4

Lower the heat and simmer, uncovered, for 45–60 minutes, until the dal is cooked through, and the liquid has reduced. Drain half of the dal and place in a blender with some of the cooking liquid. Process to a purée and pour back into the pan. Stir until well blended. The dal should have the consistency of a thick soup. Keep the dal hot.

Step 5

Make the tempering. Heat the ghee or oil in a non-stick frying pan, add the dried red chillies and cumin seeds.

Step 6

When the seeds start to crackle, add the onions and cook for 12–15 minutes, stirring occasionally, until caramelised. Stir in the ginger and tomato. Cook for two minutes, until the tomato is soft. Add the vegetable garam masala, stir well and leave to simmer for 30 seconds.

Step 7

Pour the whole tempering mixture into the simmering dal, add the chopped coriander and stir until well mixed. Simmer for three to four minutes, to allow the flavours to infuse.

Step 8

Check and adjust the seasoning to taste, adding more salt if needed, and serve hot with rice and puri.
