What each ingredient does

Mayonnaise: Provides the creamy base, fat and moisture that hold the chopped ingredients together.
Gherkins: Add sharp tang and a crisp texture that cuts through the richness of the mayonnaise.
Capers: Contribute a briny, sharp flavor that gives the sauce its characteristic bite.
Olives: Add savory, salty brininess and a firm chopped texture.
