Blood oranges are a rather gruesome name for a wonderfully sweet and beautifully colored citrus fruit. They tend to be a bit smaller than other types of oranges, with a thick, pitted skin that may or may not have a reddish blush, but they look like regular oranges from the outside. The inside flesh is brilliantly dark pink, maroon, or even dark blood red. Blood oranges grow on citrus trees in warm, temperate climates. In the U.S., they are mostly grown in California and Florida and then shipped around the country. The fruit can be eaten as is, juiced, or used in baked goods, cocktails, salads, or other dishes that call for oranges. Along with their lovely red color, blood oranges tend to have a noticeable and delicious raspberry edge to their flavor. .
