What each ingredient does
- Dal
- Its starch and protein soften and break down as it simmers, thickening the liquid into a soupy body.
- Onion
- Softened in butter, it adds sweetness and a savory aroma that flavors the whole dish.
- Butter
- Fat that carries flavor from the frying onion and adds richness to the finished dal.
The step that matters
Simmer gently and stir occasionally. Boiling hard can scorch the bottom of the pan and break the dal unevenly. A gentle simmer with occasional stirring lets it soften evenly and thicken without sticking.
