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 set with gentle heat, giving it body and a creamy texture.
- Flour
- Thickens the milk mixture, giving the dressing body so it coats the salad well.
- Butter
- Adds richness and a smooth, silky mouthfeel to the dressing.
- Sugar
- Adds sweetness that balances the sharpness of the vinegar.
- Vinegar
- Adds acidity that gives the dressing its tangy flavour.
- Milk
- Forms the creamy base that the thickened eggs and flour set into.
The step that matters
Slowly add the hot milk mixture to the egg mixture while stirring continuously.. Adding hot liquid to eggs too fast can scramble them. Adding it slowly while stirring gradually warms the eggs, so the dressing thickens smoothly instead of curdling.
