Neapolitan ice cream
Brick-shaped ice cream made up of three differently flavored ice creams (usually vanilla, chocolate and strawberry). It's normally served in slices, each of which displays the tricolored ice cream. Other desserts (or gelatin salads) made in three distinct layers are also labeled "neapolitan."
