The pomelo, Citrus maxima or Citrus grandis, is the largest citrus fruit from the Rutaceae family. It is a natural (non-hybrid) citrus fruit, similar in appearance to a large grapefruit, native to South and Southeast Asia. The pomelo is one of the original citrus species from which the rest of cultivated citrus have been hybridized. The popular fruit is used in many festive celebrations throughout Southeast Asia.
