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
- Peas
- Form the bulk of the dish and give it body and a sweet, vegetal flavour.
- Lettuce
- Softens as it stews, adding moisture and a mild, sweet vegetable note.
- Onion
- Softens and sweetens as it stews, adding savoury depth.
- Butter
- Adds fat for richness and a smooth, rounded mouthfeel.
- Egg (in the method)
- Sets when heated, thickening and enriching the liquid as it is stirred in.
- Flour (in the method)
- Thickens the cooking liquid, giving the peas a looser, creamier texture.
The step that matters
Beat an egg and stir it in. Egg proteins set when heated, so an egg added to very hot liquid can scramble into specks instead of thickening smoothly. Stirring it in steadily, with the liquid no longer boiling hard, lets it blend evenly and enrich the dish.
Swap the peas
How well each one fits the dish's main ingredients (lettuce, onion, butter, pepper):
- Sesamefits better
- Beansfits better
- Black-eyed peafits better
- Peasthe original
Fit is the average pairing score against lettuce, onion, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
