Why it works: Butter and peas are a kitchen classic. They rank in the top 16% of all ingredient pairs, and cooks put them together in 4,887 recipes. Both carry trans-2-nonenal, which smells cardboard, fatty. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Dried peas
- Provide the main body, as their starches soften and thicken the liquid during simmering.
- Oil or butter
- Adds fat for a richer mouthfeel and rounder flavour.
- Buttermilk
- Adds mild acidity and tang that brightens the soup's flavour.
The step that matters
Simmer until the peas are soft. Dried peas need a long, gentle simmer to soften fully. As their starches gelatinize, they break down and thicken the liquid. Stopping early leaves firm peas and a thin, grainy texture.
Swap the peas
How well each one fits the dish's main ingredients (butter, buttermilk):
- Almondfits better
- Pecansfits better

- Peasthe original
Fit is the average pairing score against butter, buttermilk. Candidates are from the same food group and used in at least 100 recipes.
