Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg yolks
- Thicken as they cook and bind the dressing into a smooth, creamy texture.
- Vinegar
- Supplies the sharp acidity and the liquid base of the dressing.
- Mustard
- Adds sharp flavor and helps stabilize the emulsion.
- Sugar
- Balances the sharpness of the vinegar with gentle sweetness.
The step that matters
Cook the yolk and vinegar mixture gently while stirring constantly. Egg yolks thicken as they heat, but if they get too hot or are left unstirred they can curdle or scramble. Constant stirring over the double boiler keeps the heat even so the mixture thickens smoothly.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, vinegar, cream):
- Mustardthe original
- Cucumberfits about as well
- Capsicumfits about as well
- Horseradishfits about as well
Fit is the average pairing score against egg, sugar, vinegar, cream. Candidates are from the same food group and used in at least 100 recipes.
