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
Prepare the peas
Boil the peas in 5 pints of water for about 30 minutes.
Drain and pound the peas in a mortar.
Gradually mix in the cooking liquid until smooth.
Return the mixture to the heat and simmer for 15 minutes.
Press the mixture through a fine sieve into a pot.
Make the soup
In a separate pan, melt the butter.
Sauté the cucumbers, lettuce, onions, parsley, and mint over low heat for about 1 hour, seasoning with salt and pepper.
Drain the vegetables and add them to the strained pea stock.
Simmer until the butter rises to the surface.
Add ½ to ¾ pint of 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
- Green peas
- Form the body of the soup, thickening it into a smooth purée when pounded and sieved.
- Butter
- Adds richness and a silky mouthfeel to the finished soup.
- Cucumbers
- Contribute moisture and a light, fresh flavour once softened in the pan.
- Lettuce hearts
- Soften when sautéed, adding body and a mild, sweet vegetable flavour.
- Onions
- Sweeten and deepen the flavour of the soup as they cook slowly.
The step that matters
Sautéing the vegetables over low heat. Cooking slowly softens the cucumbers, lettuce and onions gently and draws out their sweetness without browning them, which would change the pale, fresh colour and flavour of the soup.
Swap the mint
The recipe marks mint as optional. How well each one fits the dish's main ingredients (peas, butter, cucumber, lettuce, onion, white pepper, parsley):
- Tarragonfits better
- Capersfits better
- Thymefits better
- Mintthe original
Fit is the average pairing score against peas, butter, cucumber, lettuce, onion, white pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
