Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Lentils
Form the dish's main body and bulk, softening to a tender texture when boiled.
Butter
Adds fat and richness, and carries the onion flavour as it fries.
Flour
Thickens the stock into a smooth sauce that coats the lentils.
Onion
Adds sweetness and savoury depth as it softens and browns in butter.
Curry powder
Supplies the warm spiced aroma that defines the dish.

The step that matters

Adding the flour to the fried onion. Flour must be cooked briefly in the butter and onion fat before liquid goes in, otherwise it stays raw-tasting and forms lumps instead of a smooth sauce.

Swap the onion

How well each one fits the dish's main ingredients (lentils, butter, flour, pepper):

  1. Kalefits better
  2. Shallotfits better
  3. Spinachfits better
  4. Onionthe original

Fit is the average pairing score against lentils, butter, flour, pepper. Candidates are from the same food group and used in at least 100 recipes.
