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 ↓
Stewed Pease
Ingredients
Directions
Prepare
In a stewpan, combine peas, butter, onion, lettuce, and salt.
Cover and cook over moderate heat until peas are half done.
Thicken and finish
Thicken with a mixture of flour and water.
Add essence of ham, season with Cayenne pepper, and sugar if desired.
Let the peas stew gently until tender, stirring occasionally to prevent burning.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Form the body of the dish, becoming tender as they stew.
- Butter
- Adds richness and fat, carrying flavour through the stewed peas.
- Lettuce
- Releases moisture as it cooks, softening into the stew and adding body.
- Flour
- Thickens the cooking liquid into a light, cohesive sauce.
- Essence of ham
- Adds a savoury, smoky aroma and depth of flavour.
The step that matters
Let the peas stew gently until tender, stirring occasionally. Gentle heat lets peas soften without bursting, while stirring prevents the starches and sugars on the base from sticking and scorching.
