Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the mixture as they cook, giving the dressing body and structure.
- Milk
- Provides the liquid base that the eggs thicken into a creamy dressing.
- Vinegar
- Adds acidity that sharpens the flavor and balances the sweetness and richness.
- Butter
- Adds fat that makes the dressing smoother and richer in mouthfeel.
- Sugar
- Adds sweetness that balances the acidity of the vinegar.
The step that matters
Cook the mixture over medium heat while stirring constantly. Egg proteins set as they heat, so stirring constantly keeps heat even and prevents lumps or curdling. Once thickened, the dressing should be removed from heat promptly.
Swap the mustard
How well each one fits the dish's main ingredients (egg, sugar, milk, vinegar, butter):
- Capsicumfits about as well
