What each ingredient does

Caviar
Provides the main briny, salty flavour and the signature texture of the filling.
Mayonnaise
Binds the filling together and adds creamy richness that carries the caviar.
Onion
Adds sharp, aromatic bite that contrasts with the richness of the mayonnaise.
Bread
Serves as the base that holds the filling and gives each bite a neutral, soft or crisp contrast.
