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 ↓
Canned Peas
Ingredients
Directions
Prepare the peas
Drain the peas in a sieve and rinse with cold water.
Let them stand for 30 minutes to aerate.
Heat and season
Melt the butter in a saucepan over low heat.
Add the peas to the melted butter and heat slowly.
Season with coarse sea salt.
Heat one or two lettuce leaves in the butter until water is extracted.
Remove the leaves, then add the peas to heat.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Make up the bulk of the dish and provide its main body and mild sweetness.
- Butter
- Adds fat for richness and a smooth mouthfeel, and carries the flavor of the dish.
The step that matters
Heat the peas slowly over low heat. Butter can brown and turn bitter at high heat, while gentle heating warms the already-cooked peas evenly without toughening or drying them.
Swap the lettuce
The recipe marks lettuce as optional. 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.
