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 set when heated, giving it a creamy body.
- Vinegar
- Adds sharp acidity that balances the sweetness and richness.
- Milk
- Adds moisture and softness, mellowing the tang of the vinegar.
- Sugar
- Adds sweetness to balance the acidity of the vinegar.
- Mustard
- Adds sharp flavor and helps emulsify the mixture.
The step that matters
Cook while stirring constantly until thickened. Egg proteins begin to set at gentle heat, and if the mixture sits still it can curdle or scorch on the bottom. Constant stirring over a double boiler keeps heat even so the dressing thickens smoothly.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, butter, egg, vinegar, milk):
- Capsicumfits about as well
- Potatofits about as well
- Mustardthe original
- Asparagusfits about as well
Fit is the average pairing score against sugar, butter, egg, vinegar, milk. Candidates are from the same food group and used in at least 100 recipes.
