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 Stew Green Peas a Mild Way
Ingredients
Directions
Put the peas and lettuces in a stew-pan with very little water.
Stew gently until the peas are tender.
Add the cream, sugar, and egg yolks, then stir over the fire for a short time, but do not allow to boil.
Add salt before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young peas
- Form the body of the dish and provide its main sweet, fresh flavour.
- Young lettuces
- Break down while stewing to add moisture and a soft, thickened texture.
- Egg yolks
- Thicken the cream mixture into a smooth, custard-like sauce when gently heated.
- Cream
- Adds richness and fat, giving the sauce a smooth, silky mouthfeel.
The step that matters
Stirring in the egg yolks without boiling. Egg yolk proteins set when heated, but if the mixture boils they can curdle and turn grainy. Gentle heat over the fire keeps the sauce smooth and thick.
