Why it works: Lentils and onion match in chemistry and in kitchens. They rank in the top 8% of all ingredient pairs, and cooks put them together in 1,221 recipes. Both carry coumarin, which smells sweet, hay. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lentils
- Provide the main body and protein-rich bulk of the dish, setting into a thick, dry mass when cooked.
- Butter
- Adds fat and richness, carrying the curry powder's flavour and helping the onions brown.
- Onions
- Soften and brown in the fat, adding sweetness and depth to the base.
- Curry powder
- Supplies the aromatic spice flavour, released and toasted when fried in butter.
- Vegetable stock or water
- Hydrates and cooks the lentils, carrying flavour into them as they simmer.
The step that matters
Cooking the lentils until they form a dry mass. Lentils need enough liquid to cook through evenly, but the mixture must be drained and reduced to a dry mass so it does not turn soggy when combined with the fried onions and heated through.
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.
