Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolk
- Thickens the dressing as it cooks and adds richness.
- Flour
- Its starch swells with heat and thickens the dressing.
- Melted butter
- Adds fat for a smooth, rich mouthfeel.
- Vinegar
- Provides the sharp, tangy acidity that defines the dressing.
- Heavy cream
- Softens the sharpness of the vinegar and adds a creamy texture.
- Sugar
- Adds sweetness that balances the acidity of the vinegar.
The step that matters
Cooking over hot water while stirring constantly. Egg yolk and flour thicken as they heat, but too much heat can curdle or scramble the egg. Gentle, constant stirring over hot water spreads the heat evenly and keeps the mixture smooth as it thickens.
