Why it works: Parsley and pepper match in chemistry and in kitchens. They rank in the top 2% of all ingredient pairs, and cooks put them together in 34,122 recipes. Both carry 4'-methylacetophenone, which smells bitter almond. The science ↓

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Add sweetness, color, and a tender texture to the finished dish.
- Rice
- Forms the bulk of the dish and gives it a fluffy, separate-grain texture.
- Onions
- Browning in butter builds sweet, savory flavor that seasons the rice and peas.
- Butter
- Carries the onion frying and adds richness and flavor.
The step that matters
Fry the onions until lightly browned. Onions cook down slowly in fat, and browning them develops sweet, savory flavor. Burning them makes the dish bitter, while undercooked onions taste raw.
Swap the peas
How well each one fits the dish's main ingredients (rice, onion, parsley, butter, pepper):
- Black-eyed peafits better
- Beansfits better
- Chickpeafits better
- Peasthe original
Fit is the average pairing score against rice, onion, parsley, butter, pepper. Candidates are from the same food group and used in at least 100 recipes.
