The pairs that carry this dish. Each one is judged two ways: how much their aromas overlap, and how often cooks already put them together.

Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg proteins set as they heat, thickening the dressing into a smooth body.
- Vinegar
- Adds acidity that gives the dressing its sharp, tangy flavor.
- Sweet cream
- Adds fat and richness, softening the sharpness of the vinegar.
- Mustard
- Adds sharp flavor and helps keep the emulsion smooth.
The step that matters
Cooking the mixture in the double boiler. Egg proteins set at moderate heat but curdle if overheated. Gentle heat and constant stirring keep the dressing smooth and thickened rather than scrambled.
Swap the mustard
How well each one fits the dish's main ingredients (egg, vinegar, cream, pepper):
- Capsicumfits better
- Spinachfits about as well
- Mustardthe original
- Horseradishfits about as well
Fit is the average pairing score against egg, vinegar, cream, pepper. Candidates are from the same food group and used in at least 100 recipes.
