Why it works: Lettuce and peas 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 ↓
Peas, Stewed, and Lettuce
Ingredients
Directions
Prepare
Wash and remove the outer leaves from the lettuces.
Soak the lettuces in cold water for 2 hours.
Slice the lettuces into fine strips.
Make the stew
In a saucepan, combine the sliced lettuces, peas, gravy, and butter mixed with flour, sugar, pepper, and salt.
Cover the saucepan and stew until the peas are tender.

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Lettuces
- Form the body of the stew and soften into a tender, moist base as they cook.
- Peas
- Add body and gentle sweetness, becoming tender during the stewing.
- Gravy
- Supplies savoury liquid and moisture for the stew.
- Butter
- Adds richness and fat, carrying flavour through the stew.
- Flour
- Thickens the cooking liquid into a smooth, lightly bodied sauce.
- Castor sugar
- Adds mild sweetness that balances the savoury gravy and vegetables.
The step that matters
Mixing the butter with the flour. Flour blended into butter disperses evenly before it meets the hot liquid. This helps it thicken the stew smoothly instead of forming lumps that stay in the sauce.
Swap the peas
How well each one fits the dish's main ingredients (lettuce, butter, flour, sugar, pepper):
- Chestnutfits better
- Almondfits better
- Cashew nutfits better
- Peasthe original
Fit is the average pairing score against lettuce, butter, flour, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
