Why it works: Pork and ham are a kitchen classic. They rank in the top 13% of all ingredient pairs, and cooks put them together in 2,638 recipes. Both carry 2-acetyl-1-pyrroline, which smells popcorn, roasted. The science ↓

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 long boiling to thicken the soup and give it body.
- Lean salt pork
- Adds savory fat and meaty flavor as it simmers into the broth.
- Ham
- Contributes salty, smoky meat flavor to the broth.
- Split crackers
- Add starch that helps thicken the soup further.
The step that matters
Stir frequently to prevent burning. Split peas are dense and sink toward the bottom of the kettle, where they can scorch during a long simmer. Regular stirring keeps them suspended and heats the soup evenly.
Swap the peas
How well each one fits the dish's main ingredients (pork, ham, pepper):
- Beansfits better
- Black-eyed peafits better
- Lima beansfits about as well
- Peasthe original
Fit is the average pairing score against pork, ham, pepper. Candidates are from the same food group and used in at least 100 recipes.
