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 ↓
Haricot Beans
Ingredients
Directions
Cook the beans
Soak the haricot beans in cold water overnight.
Put the beans in a saucepan with 3 pints of cold water and ½ oz. of clarified dripping.
Bring to a boil, then reduce heat and simmer gently for 2 hours.
Drain the beans in a colander and return them to the dry saucepan with 1 oz. of butter.
Season and serve
Wash and dry the parsley, then chop it finely.
Sprinkle the chopped parsley over the beans and season with pepper and coarse sea salt.
Heat the saucepan and stir the contents carefully for about 5 minutes.
Serve the beans on a hot 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, becoming tender and creamy through long simmering.
- Clarified dripping
- Adds fat and savoury richness to the cooking water.
- Butter
- Adds fat and a smooth, rich mouthfeel when tossed with the warm beans.
The step that matters
Simmer gently for 2 hours. A rolling boil can break up the beans and wrinkle their skins, while gentle simmering lets them soften evenly without falling apart.
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.
“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.
