A large, pale yellow citrus fruit, the grapefruit originated in China. Nowadays, it is grown in most hot countries.
The flesh of the grapefruit tends to be acidulous and therefore slightly bitter. There are a number of varieties but they belong to either one of two classes, one having white pulp and the other pink. The pink grapefruit has the sweeter flesh.
It is, like all citrus fruit, a good source of Vitamin C.
Grapefruit makes an excellent first course for a meal, served uncooked or lightly grilled . It may also be used in fruit salads, marmalades and some cold soups.
