Why it works: Parsley and lemon 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, Maitre D'hotel
Ingredients
Directions
Cook the beans
Blanch and boil the haricot beans until tender, then drain them.
Melt a small piece of butter in a stew pan, add the beans, and season with salt and pepper.
Finish and serve
When warmed through, mix in chopped parsley and chives.
Thicken with a spoonful of white sauce and flavor with lemon juice.
Shake well over the heat for a few minutes, then dish up and serve.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Haricot beans
- Provide the main body of the dish, becoming tender when boiled.
- Butter
- Adds richness and a silky coating that carries the seasoning.
- White sauce
- Thickens the beans slightly so they cling together in a creamy coating.
- Lemon juice
- Adds acidity that brightens the buttery, herbed flavor.
The step that matters
Adding the white sauce. Stirring in too much white sauce or letting it sit over heat can make the dish heavy or cause it to scorch. A single spoonful, shaken gently over low heat, thickens the coating evenly without clumping.
Swap the beans
How well each one fits the dish's main ingredients (butter, pepper, parsley, chive, sauce, lemon):
- Chickpeafits better
- Chestnutfits about as well
- Black-eyed peafits about as well
- Beansthe original
Fit is the average pairing score against butter, pepper, parsley, chive, sauce, lemon. Candidates are from the same food group and used in at least 100 recipes.
