Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the dressing and give it a rich, creamy body as they set with gentle heat.
- Cornstarch
- Thickens the dressing during cooking so it holds texture when cooled.
- Vinegar
- Adds acidity that brightens the dressing and balances its richness and sweetness.
- Heavy cream
- Adds lightness and softness when folded in, mellowing the sharpness of the vinegar.
- Butter
- Adds fat for smoothness and a silky mouthfeel to the finished dressing.
The step that matters
Gradually add the hot vinegar to the mixture while beating continuously.. Adding hot liquid too quickly to beaten eggs can scramble them. Adding it slowly while beating tempers the eggs so the mixture stays smooth and thickens evenly.
