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 cook and set, giving it body.
- Vinegar
- Adds acidity that gives the dressing its tangy flavour.
- Mustard
- Adds sharpness and helps emulsify the dressing.
- Sugar
- Balances the acidity of the vinegar with sweetness.
- Butter
- Adds richness and fat, softening the flavour and texture.
- Sweet cream
- Adds richness and a smooth, creamy texture when folded in after cooling.
The step that matters
Cook over low heat until thickened. Eggs thicken as their proteins set, and high heat can curdle them into lumps. Gentle, steady heat with constant stirring gives a smooth, thick dressing.
