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 ↓
Plain Pease Soup
Ingredients
Directions
Make the soup
Combine split peas, celery, and broth or water in a large pot.
Simmer gently over low heat for 3 hours, stirring every 15 minutes to prevent burning.
If the soup thickens too much, add boiling water as needed.
Once softened, strain the soup through a coarse sieve, then through a fine sieve.
Finish and serve
Return the strained soup to the pot and bring to a boil, skimming off any scum.
Serve with fried bread and dried mint on the side.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Split peas
- Break down during long simmering to thicken the soup and give it body.
- Celery
- Adds aromatic flavour to the broth as it simmers.
- Broth or soft water
- Serves as the cooking liquid that softens the peas and celery into soup.
The step that matters
Simmering on low heat with regular stirring. Split peas are starchy and settle on the bottom of the pot, so they can scorch and stick at a high heat. Gentle heat and stirring keep them from burning while they soften slowly into a smooth, thick soup.

- Celerythe original
Fit is the average pairing score against peas, pepper, mint, bread, sugar. 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).
