Ingredients
Directions
Prepare the beans
Cut the young beans into slips.
Boil the beans in plenty of water with salt until tender, then drain them.
Make the sauce
In a saucepan, melt the butter over low heat.
In a bowl, beat the egg yolks with the cream.
Once the butter is hot, add the vinegar and the beans.
Stir in the egg yolks and cream mixture, simmer for 5 minutes, stirring constantly 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 and butter into a smooth, coating sauce when gently heated.
- Butter
- Adds richness and fat, giving the beans a silky texture and flavour.
- Cream
- Adds moisture and richness, softening the egg yolks into a smooth sauce.
- Vinegar
- Adds a light acidity that brightens the rich butter and cream.
The step that matters
Stirring in the egg yolk and cream mixture. Egg yolks curdle if they overheat or sit still over direct heat. Keep the heat low and stir constantly during the 5-minute simmer so the mixture thickens smoothly instead of scrambling.
