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
- Beans
- Make up the bulk of the dish; their starch cooks into a soft, creamy texture.
- Butter
- Adds fat and richness, giving the beans a smooth, glossy finish.
- Dripping
- Adds fat and savoury flavour to the cooking liquid.
The step that matters
Gently boil the beans for 2 hours. A gentle simmer cooks the beans evenly while keeping their skins intact. A hard, rolling boil tumbles them about, so they split and turn mushy.
Swap the beans
How well each one fits the dish's main ingredients (butter, parsley, pepper):
- Chickpeafits better
- Black-eyed peafits about as well
- Walnutfits about as well
- Beansthe original
Fit is the average pairing score against butter, parsley, pepper. Candidates are from the same food group and used in at least 100 recipes.
