Why it works: Pepper and onion 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 ↓

Butter and flour barely smell alike, yet cooks put them together in 124,287 recipes: they work on texture and structure more than aroma.
Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Green peas
- Form the main body of the dish and provide its vegetable base.
- Egg
- Thickens the mixture and gives it a richer, smoother body when gently heated.
- Butter
- Adds fat and flavour when used to sauté the onion.
- Onion
- Provides savoury aroma and flavour as it softens in butter.
- Flour
- Helps thicken the egg mixture so it coats the peas.
The step that matters
Heat the mixture but do not let it boil. Egg proteins in a thickened mixture can curdle and turn grainy when boiled, so gentle heat keeps the sauce smooth.
Swap the peas
How well each one fits the dish's main ingredients (butter, egg, pepper, onion, sugar, flour, sauce):
- Chestnutfits better
- Almondfits better
- Sesamefits better
- Peasthe original
Fit is the average pairing score against butter, egg, pepper, onion, sugar, flour, sauce. Candidates are from the same food group and used in at least 100 recipes.
