How to Cook Dal (Any Dal)
Also known as: dal ratios, cooking lentils
What this guide solves
One method that covers every dal in the cupboard — moong, masoor, toor, chana, urad, rajma — by sorting them into the two classes they actually belong to: quick-cooking split dals and slow, dense whole ones. Ratios, timing and the salt rule that separates creamy from gritty.
Where it goes wrong
Most kitchens treat dal as one ingredient and give it one treatment. Split moong collapses in ten minutes while chana and whole urad sit gritty for an hour in the same pot, because they are different seeds with different structures. The failures trace back to three habits: one water ratio for everything, salt and tomato added at the start, and doneness judged by the clock instead of by the dal itself.
The method
- 1. Rinse two or three times — Changes of water lift the surface starch that makes dal scum over. Pick over whole dals for small stones — a pack of rajma always hides one.
- 2. Sort your dal into its class — Quick split dals — moong, masoor, toor — cook in 10–15 minutes under pressure. Slow ones — chana, whole urad, whole rajma — need 25–40. The class decides everything downstream.
- 3. Water at 1:3 for split, 1:4 for whole — By volume. Split dals drink less because they cook apart; whole ones swell tight and need the depth to stay covered.
- 4. Add salt only after the dal softens — Anything salty or acidic early — tomato, tamarind, lemon — slows the breakdown of the skin, which is the usual cause of dal that cooks forever and still bites firm.
- 5. Test against the side of the spoon — Press a grain into the spoon; done dal smears without resistance. A grain that holds its shape is undercooked no matter what the clock says.
- 6. Finish with the tadka last — Tempered spices go over the finished dal, never boiled into it — their aroma survives seconds in hot fat, not twenty minutes under pressure.
Pro tips
- In a pressure cooker, count whistles instead of minutes: two for split dals, four to five for chana and rajma, then let the pressure fall on its own before opening.
- A pinch of baking soda genuinely speeds chana and rajma — an eighth to a quarter teaspoon per cup. More than that turns them mushy and faintly soapy.
- Kidney beans (rajma) must reach a full rolling boil before eating — undercooked kidney beans carry a natural toxin. Ten minutes of hard boiling, then cook through; never warm-hold them partway done.
- Cooked dal freezes well for a month. Freeze it plain and slightly under-seasoned, then thaw and finish with a fresh tadka.
