Why it works: Lentils and shallot share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 20 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 bulk, softening into a thick, tender stew.
- Butter
- Adds richness and fat, carrying flavor and giving the stew a smooth mouthfeel.
- Flour
- Thickens the stew as it heats, giving it body and a looser sauce.
- Shallots
- Add a mild, savory aroma and light sharpness to the base.
The step that matters
Boil gently for 10 minutes. Thickening with flour needs enough heat to cook out its raw starchy taste and fully thicken the liquid, but a hard boil can break up the lentils and scorch the bottom of the pan, so keep the heat gentle.
Swap the onion
How well each one fits the dish's main ingredients (lentils, butter, parsley, sugar, pepper, shallot, flour):
- Chivefits better

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