Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs
What each ingredient does
- Eggs
- Thicken the dressing as they set with gentle heat and add richness.
- Butter
- Adds fat for richness and a smooth, velvety mouthfeel.
- Milk
- Adds moisture and makes the dressing creamy and pourable.
- Vinegar
- Adds sharp acidity that balances the richness of the eggs and butter.
- Mustard
- Adds sharp flavour and helps bind the butter into the mixture.
The step that matters
Cook gently until thickened like cream. Egg proteins thicken the liquid as they heat and set. If the heat is too high, the eggs can curdle or scramble, leaving a grainy dressing. Gentle heat and steady stirring keep it smooth and thick.
Swap the mustard
How well each one fits the dish's main ingredients (egg, butter, milk, vinegar, pepper):
