Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Proteins set as they heat, thickening the dressing into a creamy body.
- Vinegar
- Adds sharp acidity that balances the sweetness and richness.
- Milk
- Adds moisture and softens the tang for a smoother dressing.
- Sugar
- Balances the acidity and sharpness with sweetness.
- Olive oil or melted butter
- Adds fat that gives the dressing a richer mouthfeel.
- Mustard
- Adds sharp flavor and helps hold the dressing together.
The step that matters
Stir in the double boiler until thick. Egg proteins thicken gently as they heat. If the mixture gets too hot or is left unstirred, the eggs can curdle or scramble, so keep the heat moderate and stir steadily until it thickens.
Swap the mustard
How well each one fits the dish's main ingredients (sugar, olive, egg, vinegar, milk):
- Capsicumfits better
- Cucumberfits about as well
- Mustardthe original
