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
- Provide the main body and sweet, vegetal flavor of the dish.
- Lettuce
- Softens into the stew, adding moisture and a mild, tender texture.
- Egg yolk
- Thickens the liquid gently as it heats, giving the stew a smoother, richer body.
- Cream
- Adds fat and richness, softening the flavor and smoothing the texture.
The step that matters
Do not let the mixture boil after adding the egg. Egg yolk proteins set and can curdle or turn grainy when overheated, so the mixture should be kept hot but below a boil once the yolk and cream go in.
Swap the peas
How well each one fits the dish's main ingredients (lettuce, sugar, egg, cream, pepper):
- Chestnutfits better
- Walnutfits better
- Pistachiofits better
- Peasthe original
Fit is the average pairing score against lettuce, sugar, egg, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
