Citrus never becomes boring when you mix together juice from a variety of fruits, including grapefruits, oranges, tangerines, and tangelos. Add pomegranate juice for a dose of color, flavor, and antioxidants.
Use a citrus press or a juicer to juice the grapefruits, oranges, tangerines, and lime. Juice the pomegranates (2/3 cup juice) into a separate bowl. Divid citrus juice among 3 glasses. Top with pomegranate juice, which will settle to the bottom, and serve.
