Why it works: Peas and mint are a kitchen classic. They rank in the top 2% of all ingredient pairs, and 1,137 recipes mention both. Both carry 1-octen-3-ol, which smells mushroom, earthy. The science ↓
The recipe
Ingredients
Contains: milk (auto-detected from the ingredients and method; we can miss things, so check labels)
Directions
Prepare the liquid
Wash the pea shells thoroughly and boil them in salted water for 20 to 30 minutes until tender.
Strain the shells and press the pods with a wooden spoon to extract the liquid.
Measure the liquid and pour 2 quarts into a clean saucepan. Bring to a boil.
Simmer the soup
Add 1 quart of green peas, chopped cucumbers, chopped lettuces, and thinly sliced onion that has been stewed in butter for 30 minutes.
Add parsley and mint leaves, then simmer gently for 1 hour.
Season with salt and white pepper or cayenne to taste.
Finish and serve
Press the mixture through a fine sieve, heat again, and serve with small fried snippets.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Provide the main body of flavour and a soft, thickening texture when simmered and pressed.
- Lettuces
- Add soft leafy bulk and mild sweetness that rounds out the soup's body.
- Cucumbers
- Contribute moisture and a light, fresh character to the simmered soup.
- Onion
- Adds savoury depth and aroma, mellowed by slow stewing in butter.
- Butter
- Carries the onion's flavour and adds richness to the soup base.
The step that matters
Press the mixture through a fine sieve. Pressing cooked peas, lettuce and cucumber through a fine sieve breaks down their cell walls and removes fibrous bits, giving the smooth, even texture the soup depends on. Skipping or rushing this leaves a grainy result.

Fit is the average pairing score against peas, cucumber, lettuce, onion, butter, parsley, mint. Candidates are from the same food group and used in at least 100 recipes. This compares flavor only: it does not check the job the ingredient does in the dish (bulk, moisture, acidity, structure).
