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 ↓
String Beans, Maitre D' Hotel
Ingredients
Directions
Prepare the beans
Cook the string beans as in the previous recipe.
When done, immerse them in cold water.
Drain them in a colander and place on a napkin to absorb moisture.
Finish in butter
In a flat saucepan, melt the butter and add the beans.
Season with salt and pepper, then toss over heat until warm.
Add the chopped parsley and a few drops of lemon juice before serving.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- String beans
- Form the main body of the dish and carry the butter and seasoning.
- Butter
- Adds richness and a silky coating that carries the flavour of the seasoning.
- Parsley
- Adds fresh, herbal aroma that brightens the buttery beans.
- Lemon juice
- Adds a small amount of acidity that lifts the flavour of the butter.
The step that matters
Drain and dry the beans before buttering. Surface water dilutes the butter and stops it coating the beans, so drying on a napkin lets the butter cling and keeps the dish from tasting watery.
Swap the beans
How well each one fits the dish's main ingredients (butter, pepper, parsley, lemon):
- Chickpeafits better
- Walnutfits about as well
- Pistachiofits about as well
- Beansthe original
Fit is the average pairing score against butter, pepper, parsley, lemon. Candidates are from the same food group and used in at least 100 recipes.
