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 for a Dish
Ingredients
Directions
Prepare the beans
Cut young beans into slips.
Boil beans in plenty of water with salt to preserve their color.
Once cooked, drain and dry the beans.
Make the cream sauce
In a saucepan, melt butter over low heat.
Beat egg yolks with cream and add to the melted butter.
When hot, stir in vinegar and add the beans.
Simmer for five minutes, stirring continuously to prevent burning or curdling.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Young beans
- Provide the main vegetable body of the dish.
- Egg yolks
- Thicken the cream sauce as they gently set with heat, giving it body.
- Cream
- Adds richness and a smooth, silky texture to the sauce.
- Fresh butter
- Adds fat and richness, carrying flavor and smoothing the sauce.
- Vinegar
- Adds a sharp acidity that balances the richness of the butter and cream.
The step that matters
Simmering the egg yolk sauce. Egg yolks thicken by gentle heat but curdle if overheated. Keeping the heat low and stirring constantly keeps the sauce smooth and prevents the yolks from scrambling or the butter from burning.
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.
