Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken as they cook, giving the dressing its body and structure.
- Vinegar
- Adds acidity and sharpness, and helps the eggs set when heated.
- Sugar
- Adds sweetness to balance the sharp vinegar and mustard.
- Flour
- Thickens the dressing as it cooks, stabilizing the mixture.
- Butter
- Adds richness and a smoother, rounder mouthfeel.
The step that matters
Cook the egg and vinegar mixture until thick. Eggs thicken with gentle heat but can scramble if overheated. Cooking slowly and stirring keeps the dressing smooth and creamy.
