Visit Australia…….
A highlight of Australia, the Peanut ButterTree, or Bunchosia glandulifera, produces a reddish-orange fruit that tastes and smells like peanut butter, and even has a similar texture. The fruit is the size of a quail egg and needs to be picked every day as they spoil quickly on the tree. They can be stored for several days in the refrigerator or can be separated from the seed and frozen. The skin is very tender with rich, sweet flesh that has a texture very similar to peanut butter or a sweet potato. The concentrated sugars of the fruit make it much like a dried fig.
The red fruit, of course, bears no relationship to the actual contents of peanut butter, but Australians do spread it on bread for a similar effect and they have been known to blend into a milkshake!
