Why it works: Peas and mint are a kitchen classic. They rank in the top 2% of all ingredient pairs, and cooks put them together in 1,137 recipes. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
Green Pease Soup
Ingredients
Directions
Prepare the peas
Shell the peas, separating old ones into one bowl and young ones into another. Reserve 1 pint of young peas.
Boil a large saucepan half full of water.
When boiling, add the peas and a handful of salt.
Cook for 20-30 minutes until tender.
Drain the peas in a colander.
Transfer them to a clean gallon stew pan.
Make the soup
Add 3 quarts of broth and cover.
Simmer gently over low heat for 1 hour.
Stir in the bread crumbs.
Rub the mixture through a fine sieve into another pan.
If the soup is too thick, add more broth.
Add the reserved young peas.
Season with salt and sugar.
Finish and serve
Slice the cucumbers, remove seeds, drain on a cloth, flour them, and fry in butter until light brown.
Add the fried cucumbers to the soup just before serving.
If the soup isn't green enough, pound pea hulls or spinach and squeeze the juice into the soup.
Add mint leaves if desired.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Form the body and green flavour of the soup once cooked and sieved.
- Veal or mutton broth
- Supplies the liquid base and savoury flavour of the soup.
- Bread crumbs
- Thicken the soup and give it a fuller, smoother body.
- Cucumbers
- Add a golden, lightly browned fried element with a contrasting texture.
- Butter
- Fat for frying the cucumbers, adding browning and rich flavour.
The step that matters
Rub the mixture through a fine sieve. Pushing the cooked peas through a fine sieve breaks down their cell walls into a smooth purée. Skipping or rushing this leaves a grainy soup with pea skins in it.
Swap the spinach
The recipe marks spinach as optional. How well each one fits the dish's main ingredients (peas, veal, bread, sugar, cucumber, butter, mint):
- Asparagusfits better
- Shallotfits better
- Lettucefits better
- Spinachthe original
Fit is the average pairing score against peas, veal, bread, sugar, cucumber, butter, mint. Candidates are from the same food group and used in at least 100 recipes.
