What each ingredient does
- Dal
- Forms the main body of the dish, thickening into a soft, spoonable texture as it cooks.
- Butter
- Adds fat and richness to the onion and carries its flavor through the dish.
- Onion
- Builds savory depth and aroma as it softens and browns in the butter.
The step that matters
Simmering the Dal. Simmering gently with occasional stirring keeps the lentils from scorching on the bottom and breaking down unevenly. A hard boil can cause the pulses to split and stick, so the texture and flavor suffer.
