Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Peas
- Break down into a sieved purée that thickens the soup and gives it body.
- Bacon
- Renders fat into the pot, adding savoury flavour to the soup.
- Onions
- Soften during long simmering, adding sweetness and aromatic depth to the broth.
The step that matters
Rubbing the boiled peas through a sieve. Peas must be fully cooked before sieving so they pass through smoothly; under-cooked peas stay grainy and do not thicken the soup evenly.
Swap the peas
How well each one fits the dish's main ingredients (onion, pepper):
- Black-eyed peafits better
- Sesamefits better
- Beansfits better
- Peasthe original
Fit is the average pairing score against onion, pepper. Candidates are from the same food group and used in at least 100 recipes.
