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 simmering to thicken the soup and give it body.
- Streaked bacon
- Adds smoky, savoury fat that flavours the broth.
- Veal or beef
- Adds meaty flavour and richness to the broth.
- Onions
- Build savoury sweetness and aroma as the base flavour.
The step that matters
Simmering until the peas are pureed. The peas must soften fully and the liquid must reduce by half. Peas that are undercooked stay grainy, and too little reduction leaves the soup thin, so simmering long enough matters.
Swap the peas
How well each one fits the dish's main ingredients (onion, veal, parsley, thyme, sugar):
- Chestnutfits better
- Chickpeafits better
- Lentilsfits better
- Peasthe original
Fit is the average pairing score against onion, veal, parsley, thyme, sugar. Candidates are from the same food group and used in at least 100 recipes.
