GELATO = less fat + no air added = rich cremier taste
Gelato and some premium ice creams are so dense that they require a slightly higher serving temperature, a perfect point where your scoop is firm but not hard and not so soft that it melts immediately.
Sorbets are all about fruit. With no milk, cream or eggs, they depend only on sugar, lemon juice and fresh fruit for flavor. Elegantly simple and refreshingly tart, sorbets were the rage during Victorian years, when they were served as palate cleansers between rich, heavy courses.
