Ghost apples are not a type of fruit that can be consumed. The phenomenon where freezing rain covers a rotting apple before they fall and when the cold turns them mushy it slips out and leaves the icy shell hanging on the tree. As the ice melts, the remaining apple pulp may slough off, leaving behind a translucent, ghostly-looking shell of the apple's skin and some remaining juice.

They are not apples that can be eaten but they are just snow in the form of apples and the best part is they are formed naturally. This phenomenon is primarily seen in late winter or early spring when conditions are right. While the apples themselves may still be on the tree, they are typically not edible due to the freezing and thawing process that renders them mushy and unpalatable.
And therefore, it is not a fruit, but a crystal of ice formed around an apple. It looks really beautiful!
