Seville Oranges

Tart oranges grown in the Mediterranean that are also called sour and bitter oranges. They are relatively small and contain only about 2 tablespoons of potent juice per orange. Sour oranges are used daily in the Cuban and Caribbean kitchen because of their unique sweet, sour, and acidic flavor. They are also the orange, of choice from which to make marmalade. If Seville oranges are not available, mix equal parts of fresh orange and lime juices.
