The same structure as the red lentil dal but with a pulse that holds its shape longer and takes three times as long, which makes it a different dish rather than a slower version of the same one.
- Split peas into the pan with 1 litre of water, the turmeric and the salt. Brought to the boil, skimmed, then simmered 45 to 55 minutes until soft.
- While it cooks, the tarka. Small pan or a corner of the same one once the peas are done: oil until it shimmers, dried onion until it is properly golden, then garlic and chilli for thirty seconds, then cumin for ten.
- Pour the whole lot into the dal and put the lid on for a minute. The noise it makes going in is the point, and trapping the steam puts the aroma into the pulses rather than the air.
- Lemon juice off the heat.
Turmeric goes in at the start with the water, not in the tarka. It needs the long cook to lose its raw edge and it colours the pulses as they soften.
