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

What each ingredient does

Black-eyed peas: Provide the main body and starchy texture that thickens the soup.
Collard greens: Add tender leafy texture and absorb flavor during the long, slow cook.
Ham: Adds savory, salty flavor that seasons the broth as it cooks.
Onions: Build a sweet, savory aromatic base as they soften in the broth.
Cider vinegar: Adds a bright acidity that balances the rich, earthy flavors of the soup.

The step that matters

Stir in cider vinegar just before serving. Acid is volatile and loses its brightness during long cooking, so adding vinegar at the end keeps its sharp flavor noticeable in the finished soup.
