I took away a bagful of these last year from a garden swap event. They're called
cucamelons here in UK.
The person growing them said they were simplicity itself to grow and very very productive , hence the amount of fruit she was giving away.
The downside is that the family didn't like them; I put a couple in salads and after a few tries they then got left.
The skin is hard, and the fruit is very crunchy and quite tart, not sweet as you might expect from the melon part of the name. Much more cucumber than melon, but without the refreshing juice of a cucumber.
I think its an acquired taste, I didn't dislike them but on the other hand they didn't grab me
So I won't be growing them this year.
I couldn't get Jenise's link to work, but theres an ecstatic article "
the cutest food known to man" about them here with pictures of one sliced open and how to grow, serve and pickle them.
