Why it works: Peas and lettuce match in chemistry and in kitchens. They rank in the top 5% of all ingredient pairs, and cooks put them together in 1,293 recipes. Both carry 2-isobutyl-3-methoxypyrazine, which smells green bell pepper, earthy. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Form the main body of the dish, giving it bulk and their sweet, tender texture when cooked.
- Butter
- Adds fat and moisture, enriching the peas and helping them cook gently in the covered pan.
- Lettuce leaves
- Lie under the peas, adding moisture and a mild, sweet, gentle flavour as they steam.
The step that matters
Cook tightly covered for 30 minutes. A tight lid traps steam so the peas cook in their own moisture. If the lid lets steam escape or the heat is too high, the pan can dry out and scorch before the peas are tender.
Swap the lettuce
How well each one fits the dish's main ingredients (peas, butter):
- Asparagusfits better
- Shallotfits better
- Leekfits better
- Lettucethe original
Fit is the average pairing score against peas, butter. Candidates are from the same food group and used in at least 100 recipes.
