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 ↓
To Cook Peas
Ingredients
Directions
Prepare
Shell and wash the peas, or use good canned peas.
Cook
In a saucepan, combine peas, butter, lettuce leaves, onion, salt, pepper, sugar, and water.
Cook slowly over moderate heat, stirring occasionally. If water evaporates too much, add 1 more tablespoon of water.
When done, remove the onion and lettuce.
Add cream or milk and cook for an additional 30 minutes.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Form the body of the dish, cooking down to a tender, soft texture.
- Butter
- Adds richness and fat, giving the peas a smooth, silky mouthfeel.
- Lettuce
- Contributes moisture and a mild sweetness as it softens during slow cooking.
- Cream or milk
- Adds fat and creaminess, thickening the cooking liquid into a smooth sauce.
The step that matters
Adding the cream or milk and cooking for 30 minutes. Dairy can curdle or scorch if it boils hard or sticks to the pan. Cooking slowly over moderate heat, with occasional stirring, keeps the sauce smooth and prevents the bottom from burning.
Swap the peas
How well each one fits the dish's main ingredients (butter, lettuce, onion, pepper, sugar, cream):
- Chestnutfits better
- Beansfits better
- Sesamefits better
- Peasthe original
Fit is the average pairing score against butter, lettuce, onion, pepper, sugar, cream. Candidates are from the same food group and used in at least 100 recipes.
