Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the dressing as they heat and help bind it into a smooth, creamy body.
- Flour
- Its starch swells with heat and thickens the milk mixture so it coats the spoon.
- Milk
- Provides the liquid base and mild richness that makes up most of the dressing.
- Butter
- Adds fat for richness and a softer mouthfeel.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Vinegar
- Adds acidity that gives the dressing its tang.
The step that matters
Slowly stir the hot milk into the egg mixture. Adding hot milk gradually warms the eggs little by little. If it goes in too fast, the egg proteins can set in lumps or scramble instead of blending into a smooth, thickened dressing.
Swap the mustard
