Why it works: Onion and pepper are a kitchen classic. They rank in the top 11% of all ingredient pairs, and cooks put them together in 68,474 recipes. Both carry 2-isopropyl-3-methoxypyrazine, which smells earthy, pea. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Split peas
- Form the bulk of the dish and thicken it as they soften and break down during simmering.
- Onions
- Add sweetness and savory depth when fried golden in butter.
- Curry powder
- Provides the spice aroma that defines the dish.
- Gravy or broth
- Supplies the cooking liquid that the peas absorb and that gives savory flavor.
The step that matters
Let the mixture simmer until the peas are tender. Split peas need sustained gentle simmering in enough liquid to soften fully. Stopping early leaves them firm, while too vigorous a boil can scorch the bottom of the pot and break the peas apart unevenly.
Swap the peas
How well each one fits the dish's main ingredients (onion, butter, pepper):
- Black-eyed peafits better
- Sesamefits better
- Beansfits better
- Peasthe original
Fit is the average pairing score against onion, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
