Blood oranges are a variety of orange known for their distinctive deep red or maroon-colored flesh. This unique coloration is due to the presence of anthocyanins, a type of antioxidant that is not typically found in other orange varieties. Blood oranges are usually smaller than regular oranges and have a slightly sweeter, more complex flavor, often described as a mix of orange and raspberry. These oranges are primarily grown in Mediterranean regions, such as Italy and Spain, where the climate is ideal for their development. They are typically in season from December to April and can be enjoyed fresh, juiced, or used in various culinary dishes.
