Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Egg proteins set as the mixture heats, thickening the dressing into a creamy consistency.
- Melted butter
- Adds fat, giving the dressing richness and a smooth mouthfeel.
- Sweet cream
- Adds fat and body, making the dressing creamier and milder in tang.
- Vinegar
- Supplies acidity, giving the dressing its sharp, tangy flavor.
- Mustard
- Adds sharp flavor and helps emulsify the fat into the dressing.
The step that matters
Cook over low heat, stirring constantly. Egg proteins set at gentle temperatures, so low heat with constant stirring keeps the dressing smooth. Higher heat or pauses can scramble the eggs into lumps.
