Why it works: Cucumber and lettuce match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 1,409 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓
Green Peas Soup, Without Meat
Ingredients
Directions
Cook and strain the peas
Boil the peas in 3 quarts of water with salt for about 30 minutes.
Drain and pound the peas, then mix with 5 pints of the boiling water.
Return the mixture to the heat and simmer gently for 15 minutes.
Press the mixture through a fine sieve.
Cook the vegetables in butter
In a separate pan, simmer butter, cucumbers, lettuce, onions, parsley, and mint for nearly an hour, stirring occasionally.
Season with salt and white pepper or cayenne.
Combine and serve
Drain the vegetables from the butter and add them to the strained stock.
Boil gently until the butter rises to the surface.
Add the young peas and serve immediately.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Large green peas
- Once pounded and sieved, they provide the body and thickness of the soup.
- Butter
- Carries flavour during cooking and adds richness and a smooth mouthfeel.
- Cucumbers
- Add watery moisture and a light, fresh flavour as they cook.
- Lettuce
- Softens as it cooks, adding body and a mild sweetness.
- Onions
- Soften in the butter, adding a savoury aroma to the base.
- Mint
- Adds a fresh, aromatic lift to the soup.
The step that matters
Press the mixture through a fine sieve. Pushing the cooked peas through a fine sieve breaks down the remaining fibres and skins, giving the soup a smooth texture. Skipping or rushing this step leaves a grainy, uneven soup.
Swap the white pepper
How well each one fits the dish's main ingredients (peas, butter, cucumber, lettuce, onion, parsley, mint):
- Tarragonfits better
- Capersfits better
- Thymefits better
- White pepperthe original
Fit is the average pairing score against peas, butter, cucumber, lettuce, onion, parsley, mint. Candidates are from the same food group and used in at least 100 recipes.
