Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the dressing as it cooks and gives it body and richness.
- Butter
- Adds fat for a smooth, rich mouthfeel in the dressing.
- Cream or rich milk
- Adds fat and moisture, making the dressing creamy and mellow.
- Flour
- Helps thicken the dressing and keeps it from splitting as it heats.
- Vinegar
- Adds acidity that gives the dressing its tangy flavour.
- Sugar
- Balances the sharpness of the vinegar with a touch of sweetness.
The step that matters
Adding the vinegar slowly. Pouring vinegar in quickly can curdle the egg and cause a lumpy dressing. Adding it slowly while mixing lets the egg blend in evenly, so the dressing cooks smooth.
