Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the dressing as its proteins set when heated.
- Vinegar
- Provides the sharp acidity that gives the dressing its tang.
- Mustard
- Adds sharp flavour and helps hold the fat and liquid together.
- Butter or salad oil
- Adds fat for richness and a smooth, silky mouthfeel.
- Sour cream
- Adds creaminess and mild tang, softening the sharpness of the vinegar.
- Sugar
- Adds sweetness that balances the acidity of the vinegar.
The step that matters
Boil while stirring briskly. Egg proteins thicken the dressing when heated, but if heat is uneven they can curdle into lumps. Constant brisk stirring spreads the heat evenly and keeps the mixture smooth as it thickens.
