The flesh of the blood orange has a distinctive red color. To develop this red color, the plant requires soil with special thermal properties. As a result, blood oranges do not grow everywhere. They are widely grown in Spain and Israel, but can also be found in countries such as Brazil, South Africa, and Turkey. However, the finest blood oranges come from Italy. The rich volcanic soils of Sicily give Sicilian blood oranges their deep red color and very full flavor. Blood oranges have a fresh, tangy taste that is slightly sharper and more bitter than that of a regular orange. There are two types of blood oranges. The full-blood variety has red skin and red flesh. The half-blood variety has only red flesh. These two types of blood oranges can be divided into three varieties, which are available at different times: the tarocco (full-blood, December to April), the moro (half-blood, December to March), and the sanguinello (full-blood, February to March).
