Ranks compare each pair with 20,000 random ingredient pairs on CompKitchen. How we score pairs

What each ingredient does

Hard-boiled eggs
Yolks mashed into the dressing add body and richness; whites add chopped bulk.
Olive oil
Adds fat that carries flavor and makes the dressing smooth and rich.
Vinegar
Provides acidity that brightens the dressing and balances the oil.
Tomatoes
Contribute moisture and fresh, slightly acidic flavor to the salad.
Dry mustard
Adds sharp, pungent flavor that helps balance the richness of the egg and oil.

The step that matters

Stirring the yolks smooth before adding the oil. Mashing yolks thoroughly with the seasonings before adding oil and vinegar lets the yolk act as an emulsifier, so the dressing stays smooth rather than separating.
