Grapefruit is a citrus fruit of Indian origin, which spread first in the Americas and then in Europe. Even in Italy, particularly in the southern regions, it is widely cultivated. There are two varieties: the yellow grapefruit , with a rather acidulous pulp and the pink or red grapefruit, with sweeter pulp, varying in color between pink and bright red.

Grapefruit is usually eaten divided horizontally in half; the wedges are removed with a special teaspoon with a serrated tip, or they are first detached from the peel and then separated from each other by using a curved serrated knife.

Grapefruit is excellent natural, but it is also used as an ingredient for appetizers, thirst-quenching drinks, sorbets and juices.
