Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Add richness and help thicken the sauce as it cooks.
- Butter
- Adds richness and a smooth, silky mouthfeel to the sauce.
- Flour
- Thickens the sauce as it cooks in the boiling water.
- Sugar
- Adds sweetness and body to the sauce.
- Brandy
- Adds aroma and a warm, boozy flavour.
The step that matters
Stir the creamed mixture into the boiling water. Adding the mixture gradually and stirring constantly keeps the egg yolks and flour from clumping, so the sauce cooks smooth rather than lumpy or curdled.
“What each ingredient does” and “The step that matters” were written by Claude from this recipe’s own method and reviewed in samples by CompKitchen.
