Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the dressing as they cook, giving it a creamy, emulsified body.
- Cream or milk
- Adds moisture and richness, softening the sharpness of the vinegar.
- Vinegar
- Provides acidity that gives the dressing its tangy flavour.
- White sugar
- Balances the acidity with sweetness.
- Mustard
- Adds sharp flavour and helps stabilise the emulsion.
The step that matters
Cook over simmering water, stirring constantly. Egg proteins set gently with heat, thickening the dressing. If the heat is too high or stirring stops, the eggs can scramble and the mixture turns lumpy instead of smooth and creamy.
Swap the mustard
How well each one fits the dish's main ingredients (egg, cream, vinegar, sugar, pepper):
- Capsicumfits about as well
- Mustardthe original
- Horseradishfits about as well
- Spinachfits less well
Fit is the average pairing score against egg, cream, vinegar, sugar, pepper. Candidates are from the same food group and used in at least 100 recipes.
