Key lime juice is the distinctive ingredient in our pleasingly sweet yet tart vibrantly packaged Tortuga Taste of Florida Key Lime Rum Cake. Baked in the Caribbean with only the finest ingredients, each rum cake is hand glazed with special 5-year-old, oak barrel aged Tortuga Gold Rum then vacuum sealed to lock in the delicious freshness. The cakes have a shelf life of 9 months, or indefinitely if refrigerated or frozen.
