Why it works: Lettuce and lentils share more aroma than cooks usually use. They rank in the top 1% of all ingredient pairs, and cooks put them together in 51 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
- Break down during long simmering to thicken the soup and give it body.
- Carrots
- Add sweetness and color, and help give the soup its body when sieved.
- French roll crumbs
- Soak up liquid and help thicken the soup further.
- Butter
- Adds richness and carries flavor from the vegetables.
The step that matters
Adding more stock after simmering. The lentils and vegetables absorb liquid as they cook, so the pan can run dry and scorch. Topping up the stock keeps the mixture loose enough to simmer evenly and to pass through a sieve.
Swap the onion
How well each one fits the dish's main ingredients (carrot, lettuce, butter, lentils, rice):
- Leekfits better
- Turnipfits better
- Beetrootfits better
- Onionthe original
Fit is the average pairing score against carrot, lettuce, butter, lentils, rice. Candidates are from the same food group and used in at least 100 recipes.
