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 ↓
To Boil French Beans
Ingredients
Directions
Prepare the beans
Take off the ends and stalks of the very small, young beans, and drop them into plenty of spring water as they are done.
When all are ready, wash and drain them well.
Throw them into a large saucepan of fast-boiling salted water.
Boil until quite tender, about twelve to eighteen minutes.
Pour into a colander, shake off the water, dish, and send quickly to table with good melted butter in a tureen.
Make the sauce
Melt a couple of ounces of fresh butter in a clean saucepan and stir in a small dessertspoonful of flour.
Keep shaken and gently simmered until lightly browned, then add salt and pepper.
Pour in by degrees a small cupful of good veal gravy, or sweet rich cream.
Toss the boiled beans in the sauce until as hot as possible.
Stir in the beaten yolks of two fresh eggs and a little lemon juice, away from the fire, and serve without delay.
Nutrition, whole recipe (rough)
Counts 5 of 6 ingredients. The other 1 aren't in our nutrition table and add nothing above, so the real totals are higher.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Butter
- Melted butter forms the base of the sauce and adds richness and a silky mouthfeel.
- Flour (in the method)
- Cooked with butter, it thickens the sauce so it coats the beans.
- Eggs
- Beaten yolks enrich and thicken the sauce gently when stirred in off the heat.
- Veal gravy
- Adds savoury depth and body to the sauce.
The step that matters
Stir in the egg yolks away from the fire. Egg yolks thicken by gentle heat and can scramble or curdle if the sauce is too hot, so they are added off the heat and the sauce is served promptly.
Swap the white pepper
How well each one fits the dish's main ingredients (butter, veal, parsley, egg, pepper):
- Tarragonfits better
- Sagefits better
- Thymefits better
- White pepperthe original
Fit is the average pairing score against butter, veal, parsley, egg, pepper. Candidates are from the same food group and used in at least 100 recipes.
