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 Cream for a Dish
Ingredients
Directions
Prepare the beans
Cut the young green beans into strips.
Boil the beans in plenty of water with salt to keep them green.
Once cooked, drain and dry the beans.
Make the sauce
In a saucepan, melt the butter over low heat.
In a bowl, beat the egg yolks with the cream.
Add the egg mixture to the melted butter and heat gently.
Once hot, stir in the vinegar and 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 green beans
- Provide the main vegetable body and fresh, tender texture for the creamed dish.
- Egg yolks
- Thicken the cream and butter mixture into a smooth, custard-like sauce as they gently heat.
- Cream
- Adds richness and moisture, softening the sauce and helping it stay smooth when heated with the yolks.
- Fresh butter
- Provides fat for richness and a silky mouthfeel in the sauce.
- Vinegar
- Adds a small amount of acidity that brightens the rich butter and cream sauce.
The step that matters
Heating the egg yolk mixture gently while stirring. Egg yolks thicken through gentle heat, but if they get too hot or are left unstirred they can scramble and curdle, leaving the sauce grainy instead of smooth.
Swap the green beans
How well each one fits the dish's main ingredients (butter, egg, cream, vinegar):
