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 ↓
Green Peas Stewed
Ingredients
Directions
Stew the peas
Wash the peas and place them in a saucepan with the lettuce, onion, butter, pepper, and salt. Do not add water; the lettuce and peas will provide enough moisture.
Stew gently for 1 hour.
Finish and serve
Add a pinch of sugar, cream, and the beaten egg, stirring until it thickens without boiling.
Curl the rashers of bacon and cook them.
Serve on a hot dish, garnished with the curled bacon.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Shelled peas
- Form the main body of the dish and supply most of its flavour and texture.
- Lettuce
- Releases moisture as it cooks, so the peas stew without added water.
- Butter
- Adds fat and richness, carrying flavour through the stew.
- Cream
- Adds richness and body, and helps thicken the stew when combined with egg.
- Egg
- Sets gently in the hot liquid, thickening the stew without boiling.
The step that matters
Stirring in the egg without boiling. Egg proteins set and can curdle or turn grainy if the mixture boils. Keeping the heat low and stirring while it thickens gives a smooth, lightly thickened result.
Swap the onion
How well each one fits the dish's main ingredients (peas, lettuce, butter, pepper, sugar, cream, egg):
- Asparagusfits better
- Leekfits better
- Spinachfits better
- Onionthe original
Fit is the average pairing score against peas, lettuce, butter, pepper, sugar, cream, egg. Candidates are from the same food group and used in at least 100 recipes.
