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 during cooking, giving it a custard-like body.
- Olive oil
- Adds fat and richness, helping the dressing feel smooth on the palate.
- Mustard
- Adds sharp flavour and helps emulsify the oil into the dressing.
- Milk
- Adds creaminess and softens the sharpness of the vinegar.
- Vinegar
- Adds acidity that brightens the dressing and balances the richness.
The step that matters
Cook like soft custard. Egg proteins set gradually with gentle heat. If the heat is too high or the dressing is left unstirred, the eggs can curdle and turn grainy instead of smooth and thick.
Swap the mustard
