Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Dried green peas
Form the body and thickness of the soup as they break down during long simmering.
Bacon
Adds savoury, smoky fat that flavours the broth as it cooks.
Sorrel
Contributes a sharp, acidic brightness and fresh green flavour.
Boiled rice
Adds body and a silky thickness to the soup.
Butter
Carries flavour and adds richness when the greens are stewed.

The step that matters

Skimming while boiling. Foam and impurities rise to the surface as the soup boils. Skimming them off keeps the broth clean in flavour and colour before the long simmer.

Swap the peas
