Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg yolks thicken the dressing as they cook and give it a rich, creamy body.
- Milk or cream
- Adds moisture and richness, softening the sharpness of the vinegar.
- Vinegar
- Provides the acidity that gives the dressing its tangy flavor.
- Sugar
- Balances the acidity of the vinegar with a touch of sweetness.
The step that matters
Cooking the mixture after adding the hot vinegar. Egg yolks thicken when heated, but if the mixture gets too hot or is left unstirred, the eggs can scramble and curdle. Constant stirring over gentle heat keeps the dressing smooth and evenly thickened.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, pepper, milk, vinegar):
- Capsicumfits better
- Mustardthe original
- Asparagusfits about as well
- Cucumberfits about as well
Fit is the average pairing score against egg, sugar, pepper, milk, vinegar. Candidates are from the same food group and used in at least 100 recipes.
