Corrected entry: How would Barbarossa have such nice looking apples? He is on a dirty old pirate ship in an Atlantic setting with no orchards within 100's of miles and yet he has such flawless, ripe fruit. Apples are not a tropical fruit in nature. This means that they have to be shipped from other places by ship, if at all. The voyage would take weeks, maybe months for them to arrive. The stories about sailors having scurvy due to the lack of fresh fruit and vegetables is because fruit like apples only stay good for about a week and then start to go bad. They would never last the entirety of the voyage.
Correction: The pirates just pillaged Port Royal, including the well stocked home of the Governor. It makes sense to think that they stole all the delicious food that they now have aboard the Pearl, including the apples, from Port Royal.
