Why it works: Lemon and parsley match in chemistry and in kitchens. They rank in the top 1% of all ingredient pairs, and cooks put them together in 14,037 recipes. Both carry beta-phellandrene, which smells minty, terpene. The science ↓
Haricot Beans, Boiled
Ingredients
Directions
Cook the beans
Drain the beans and place them in a saucepan with plenty of cold water, slightly salted.
Boil gently until tender, about two hours.
Pour away the water.
Let the beans stand by the fire for a minute or two, shaking them occasionally to dry.
Season and serve
Add a small piece of butter, pepper, and salt.
Serve hot.
For variation, mix drained beans with butter, pepper, salt, lemon juice, and chopped parsley in a stewpan.

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, starchy base when boiled.
- Butter
- Adds richness and a smooth mouthfeel to the warm beans.
- Lemon juice
- Adds acidity that brightens the flavour of the rich, starchy beans.
The step that matters
Boil gently until tender. Beans need a long, gentle simmer to soften fully; a hard rolling boil can break the skins and leave the beans ragged, while stopping early leaves them firm and chalky inside.
Swap the beans
How well each one fits the dish's main ingredients (butter, pepper, lemon, parsley):
- Chickpeafits better
- Walnutfits about as well
- Pistachiofits about as well
- Beansthe original
Fit is the average pairing score against butter, pepper, lemon, parsley. Candidates are from the same food group and used in at least 100 recipes.
