Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken as they heat, giving the dressing its body and structure.
- Butter
- Adds fat for richness and a smoother, rounder mouthfeel.
- Vinegar
- Provides the sharp acidity that gives the dressing its tang.
- Sugar
- Adds sweetness that balances the acidity of the vinegar.
The step that matters
Stir constantly over the double boiler until it thickens. Egg yolks thicken gently at low, indirect heat, but they can scramble if they get too hot or sit still. Constant stirring spreads the heat evenly so the dressing thickens smoothly.
Swap the mustard
