Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Their proteins set as they heat, thickening the dressing into a creamy body.
- Melted butter
- Adds fat for richness and a smooth, rounded mouthfeel.
- Cream
- Adds fat and moisture, making the dressing softer and milder.
- Vinegar
- Provides acidity that gives the dressing its sharp, tangy flavour.
- Sugar
- Adds sweetness that balances the acidity of the vinegar.
- Mustard
- Adds sharp aroma and flavour, and helps hold the fat and liquid together.
The step that matters
Thickening over hot water. Egg proteins set when heated, so the eggs can curdle or scramble if the heat is too high or stirring stops. Gentle heat and constant stirring give a smooth, thick dressing.
