Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Emulsifier that helps hold the oil and lemon juice together as a smooth dressing.
- Lemon juice
- Adds acidity and brightness that cut through the richness of the oil and cream.
- Olive oil
- Provides fat for body, mouthfeel, and flavor.
- Sour cream
- Adds creaminess, body, and a mild tang to the dressing.
- Mustard
- Helps stabilize the emulsion and adds a sharp, savory flavor.
- Sugar
- Balances the sourness of the lemon juice and sour cream.
The step that matters
Gradually add the sour cream and mix well. Adding the sour cream slowly and mixing thoroughly lets it blend evenly into the emulsified base. Dumping it in at once can leave lumps or cause the dressing to separate.
Swap the mustard
