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.
- Meat and bones
- Release flavor and gelatin into the broth, adding richness and body.
- Salt pork
- Adds savory fat and smoky, seasoned flavor to the broth.
- Onions
- Provide sweetness and aromatic depth as they soften in the broth.
The step that matters
Simmer until the peas are soft. Split peas need sustained, gentle simmering to fully soften and break down. Stopping early leaves them firm and the soup thin and grainy. Too hard a boil can scorch the bottom of the pot and cloud the broth.
Swap the peas
How well each one fits the dish's main ingredients (meat, pork, onion, clove, pepper):
- Beansfits better
- Sesamefits better
- Chickpeafits better
- Peasthe original
Fit is the average pairing score against meat, pork, onion, clove, pepper. Candidates are from the same food group and used in at least 100 recipes.
