What each ingredient does
- Dal
- Forms the main body of the dish, thickening as it simmers and softens.
- Butter
- Adds fat and richness while softening the onion for flavour.
- Onion
- Contributes savoury aroma and sweetness as it softens in the fat.
The step that matters
Simmering the Dal gently. Keeping the heat low and stirring occasionally prevents the lentils from sticking to the base of the pan and scorching. A gentle simmer lets them soften evenly without breaking apart into a uneven texture.
