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

What each ingredient does

Old cheese: Provides the main body, rich flavor and savory bulk of the salad.
Hard-boiled egg yolk: Mashed with oil into a paste that binds and enriches the salad.
Salad oil: Adds fat and smoothness, carrying the yolk into a spreadable paste.
Onion vinegar: Adds sharp acidity that brightens the rich cheese and egg.
