Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lentils
- Form the main body of the dish, cooking down into a thick, dry mass.
- Butter or drippings
- Provide fat that carries the curry flavour and helps the onions brown.
- Onions
- Add sweetness and savoury depth when browned.
- Curry powder
- Supplies the aroma and spice flavour, which blooms when fried in fat.
The step that matters
Frying the onions until brown. Browning develops sweetness and deep savoury flavour through caramelisation and Maillard reactions. Pale onions taste flat, while over-darkened ones turn bitter.
Swap the lentils
How well each one fits the dish's main ingredients (butter, onion):
- Sesamefits better
- Peanutfits better
- Almondfits better
- Lentilsthe original
Fit is the average pairing score against butter, onion. Candidates are from the same food group and used in at least 100 recipes.
