Why it works: Lettuce and pepper are a kitchen classic. They rank in the top 9% of all ingredient pairs, and cooks put them together in 4,037 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuce
- Is the main vegetable; cooking softens its leaves until they become tender and easy to chop.
- Butter
- Adds richness and a silky mouthfeel to the cooked lettuce.
The step that matters
Drain thoroughly. Lettuce holds a lot of water after boiling. Leaving it wet dilutes the butter and pepper and makes the dish watery, so squeeze or press out as much liquid as you can before chopping.
Swap the lettuce
How well each one fits the dish's main ingredients (butter, pepper):
- Capsicumfits better
- Potatofits better
- Carrotfits better
- Lettucethe original
Fit is the average pairing score against butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
