Why it works: Pepper and parsley 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 ↓
Colored Dry Beans

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Colored dry beans
- Form the main body of the dish, becoming tender through soaking and long gentle boiling.
- Bacon
- Adds smoky, savory fat that flavors the beans and the cooking liquid.
- Butter
- Adds richness and fat that carries flavor when the beans are tossed.
- Flour
- Thickens the cooking liquid slightly, giving the sauce body.
- Claret wine
- Adds acidity and depth to the liquid as it reduces around the beans.
The step that matters
Boil gently until cooked. Dry beans need a long, gentle simmer to soften fully; a hard boil can break the skins and leave the beans mushy and uneven.
Swap the onion
How well each one fits the dish's main ingredients (beans, pepper, butter, flour, parsley, wine):
- Shallotfits better
- Chivefits better
- Carrotfits better
- Onionthe original
Fit is the average pairing score against beans, pepper, butter, flour, parsley, wine. Candidates are from the same food group and used in at least 100 recipes.
