When I got home, I tried to research the origin and history of my find online. I found some growing instructions, and a few brief tasting notes from fellow food bloggers, but nothing to indicate which fruits were spliced to create the melon, or how it got its name.
Nevertheless, I cut open the round pumpkin-orange Fonzy Melon, which is about the size of a Honeydew, for breakfast this morning. Inside was a juicy white semi-firm fruit flesh surround a core of seeds. The flavor tasted like a cross between a Bartlet Pear and a Muskmelon (Cantaloupe), which may, or may not, be a clue to its breeding.
In any case, the Fonzy Melon offers a distinctive flavor, and can be used as one would use any small melon.
