Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Egg
- Thickens the heated dressing as its proteins set, giving it body.
- Melted butter
- Adds richness and smooth fat to the dressing.
- Sweet milk
- Makes the dressing creamy and softens its sharpness.
- Vinegar
- Adds sharpness that cuts through the richness of the dressing.
- Sugar
- Balances the vinegar's sourness with sweetness.
- Onion
- Adds sharp, aromatic bite.
The step that matters
Heat the egg mixture over boiling water, stirring constantly until it thickens. Egg proteins can curdle or scramble if overheated. Gentle indirect heat from boiling water, with constant stirring, lets the mixture thicken evenly and smoothly before the vinegar is added.
