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, becoming thick and smooth when pressed through a sieve.
- Broth (mutton or veal)
- Provides the liquid base and savory depth in which the peas stew.
- Mint
- Adds a fresh, aromatic flavour that brightens the rich stewed peas.
- Toasted bread
- Adds crisp texture and contrast to the smooth soup when served.
The step that matters
Rubbing the soup through a coarse sieve. Pressing the stewed peas through a sieve breaks down their cell walls and separates the skins, giving a smooth, even texture. Skipping or rushing this leaves the soup grainy and lumpy.
Swap the mint
How well each one fits the dish's main ingredients (peas, mutton, pepper, bread):
- Parsleyfits about as well
- Mintthe original
- Marjoramfits about as well
- Celeryfits about as well
Fit is the average pairing score against peas, mutton, pepper, bread. Candidates are from the same food group and used in at least 100 recipes.
