Good luck when picking time comes - end of summer, early fall. It will ripen best on the tree. They are usually picked individually when they have a little "give".
Taste of pawpaws ... I find about half the people I give them to like the taste. About a fourth love them, and the last fourth think it is a weird taste. If you like tropical fruits you will probably at least like them.
They grow very well in Arkansas and Iowa.
Here are a few homemade pictures and links:
