citrus fruits 
Somewhat acidic fruits with a high vitamin C content comprising numerous sections and covered with a rind that has an external layer called zest.
Extensively grown in Corsica and Israel, this somewhat dry fruit is rarely found fresh and is mostly sold candied.
Extremely popular in many Asian countries, it has only recently become available in the West; less juicy than the grapefruit, it is mostly cooked or candied.
Widely available, it is often eaten plain or in juice, and it goes well with duck; it yields a flavor essence and an essential oil.
The pink grapefruit is sweeter and less bitter than the white one that has yellow flesh; it is often cut in half and eaten plain, with a spoon.
