Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens as it cooks over heat, giving the dressing body and a creamy structure.
- Mustard
- Adds sharpness and helps emulsify the dressing for a smoother texture.
- Vinegar
- Adds acidity that brightens the flavor and balances the richness.
- Whipped cream
- Lightens the thickened base and adds softness and a smooth, airy mouthfeel.
The step that matters
Cook over hot water until thick. Egg proteins set gradually with gentle heat. Overheating causes them to scramble into lumps, so keep the heat moderate and stir constantly.
Swap the mustard
How well each one fits the dish's main ingredients (egg, vinegar, pepper, butter, cream):

Fit is the average pairing score against egg, vinegar, pepper, butter, cream. Candidates are from the same food group and used in at least 100 recipes.
