Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young green peas
- Provide the bright, sweet flavour and tender body of the finished soup.
- Old green peas
- Boiled and strained to thicken the broth and add earthy pea flavour.
- Butter
- Adds richness and a smooth mouthfeel to the soup.
- French roll
- Fried and stirred in, it thickens the soup and adds body.
- Onion
- Adds savoury aromatic depth as the soup stews.
The step that matters
Let the soup stew until the young peas are tender. Young peas need sustained gentle simmering to soften fully. Stopping early leaves them starchy and firm, while overcooking dulls their bright green colour and fresh flavour.
Swap the onion
How well each one fits the dish's main ingredients (peas, butter, pepper, mint, flour):
- Shallotfits better
- Asparagusfits better
- Cucumberfits better
- Onionthe original
Fit is the average pairing score against peas, butter, pepper, mint, flour. Candidates are from the same food group and used in at least 100 recipes.
