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 ↓
Haricot Beans
Ingredients
Directions
Prepare the beans
Soak the beans overnight in cold water.
Strain the beans and let them stand for a day or two, if possible.
Cook and serve
Put the beans into a saucepan with boiling water and dripping, and add salt.
Simmer gently for two hours, or until the beans are quite soft.
Drain the beans in a colander and return them to the saucepan.
Add butter, parsley, salt, and pepper, and stir over the fire for five minutes.
Serve in a hot vegetable dish.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haricot beans
- Form the main body of the dish, softening into a tender, creamy texture when simmered.
- Butter
- Adds richness and a smooth, glossy finish when stirred into the hot beans.
The step that matters
Simmering until quite soft. Dried haricot beans need a long, gentle simmer for their starches to gelatinise and their skins to soften. Stopping early leaves them firm and unevenly cooked, while a hard boil can break them apart.
Swap the beans
How well each one fits the dish's main ingredients (butter, pepper, parsley):
- Chickpeafits better
- Black-eyed peafits about as well
- Walnutfits about as well
- Beansthe original
Fit is the average pairing score against butter, pepper, parsley. Candidates are from the same food group and used in at least 100 recipes.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
