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

What each ingredient does

Chicory: Provides the crisp, slightly bitter leaves that form the body of the salad.
Olive oil: Carries the flavor of the dressing and coats the leaves with fat for a smooth mouthfeel.
Vinegar: Adds acidity that sharpens the dressing and balances the oil.
