What do you do with dried fresh mozerella?
I'm afraid I can only answer as to what I do with dried fresh mozzerella, which may be not coincide with its usual use: Eat about a pound of it on the way to the airport whenever I'm in the NYC area and can get up to Arthur Avenue.
It looks not unlike an air-dried provolone, but as you approach the center of the cheese, it gets moister. The texture toward the outside is also like dryish provolone.
I'd love to find out what those in the know use it for. It may just be to preserve it... Thin-sliced, it would be great on a sandwich, but I've never had one which lasted long enough to test that theory.
