The botanical name of the pineapple is “Ananas Comosus”.   The pineapple neither an apple nor a pine, as its name might suggest.  It was named for its resemblance to that of a pine cone.  Believe it or not, this fruit is actually a berry!  Pineapple is very affordable even when it’s out of season, because it can be purchased fresh, canned or frozen. In fact, pineapple is the third most canned fruit behind applesauce and peaches.
