Why it works: Butter and cream are a kitchen classic. They rank in the top 8% of all ingredient pairs, and cooks put them together in 41,516 recipes. Both carry delta-dodecalactone, which smells sweet, creamy. The science ↓
French Beans , a LA Creme
Ingredients
Directions
Prepare the beans
Cut the beans into 8 pieces and soak them in water with salt.
Boil the beans in salted water until tender, being careful not to lose their green color.
Drain the beans and set aside.
Make the cream sauce
In a saucepan, melt the butter over low heat.
Beat the egg yolks with the cream and add to the melted butter.
Stir in the vinegar and the beans, simmer for 5 minutes, stirring gently to prevent burning.
Serve hot.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken the cream and butter into a smooth, rich sauce as they set gently with heat.
- Butter
- Adds fat and richness, carrying flavor and giving the sauce a silky texture.
- Cream
- Adds moisture and richness, softening the sauce and balancing the egg yolks.
- Vinegar
- Adds acidity that brightens the buttery, rich sauce.
The step that matters
Keep the sauce over low heat while simmering the beans. Egg yolks can curdle or scramble if they get too hot, and the sauce can scorch on the bottom. Low heat and gentle stirring keep the sauce smooth.
Swap the beans
How well each one fits the dish's main ingredients (butter, egg, cream, vinegar):
- Almondfits better
- Pecansfits better
- Walnutfits better
- Beansthe original
Fit is the average pairing score against butter, egg, cream, vinegar. Candidates are from the same food group and used in at least 100 recipes.
