Why it works: Cabbage and lettuce match in chemistry and in kitchens. They rank in the top 4% of all ingredient pairs, and cooks put them together in 622 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Stewed Peas
Ingredients
Directions
Melt the butter in a stew pan.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Form the main body of the dish and supply its tender, sweet flavour.
- Lettuce hearts
- Soften as they stew, adding moisture and a mild, sweet body to the peas.
- Flour
- Thickens the cooking liquid into a light sauce when mixed with butter and stirred in.
- Butter
- Adds richness and fat, and combines with flour to form the thickening paste.
The step that matters
Adding the flour and butter thickener. Flour must be mixed with butter first and stirred in while the liquid is hot so it disperses evenly. Added as lumps or to a cold liquid, it stays clumped and the sauce turns out patchy rather than smooth.
Swap the peas
How well each one fits the dish's main ingredients (butter, ham, onion, cabbage, lettuce, sugar, flour):
- Chestnutfits better
- Beansfits better
- Lentilsfits better
- Peasthe original
Fit is the average pairing score against butter, ham, onion, cabbage, lettuce, sugar, flour. Candidates are from the same food group and used in at least 100 recipes.
