Jack Fruit is an interesting fruit, it is reported to be the largest fruit in the world. It grows not from a branch, but, on the trunk of the tree. In Asia is grows to a weight of over 100 lbs. In the U.S.A. it grows much smaller I've seen them weighing 25 lbs. The flavor is similar to Juicy Fruit gum, some say that Juicy Fruit gum actual got its flavor from the Jack Fruit.
Preparing a Jack Fruit is not as easy as some fruit. Unless very ripe, it is full of latex. You need to either oil you hands and knife with vegetable oil or at least wear kitchen gloves while cutting it. Both the fruit and the seeds are edible.
