Using a small sharp knife, cut a triangular-shaped plug from the stem end of the melon.
Pur 1 cup port into into melon. Replace plug and let marinate for 4 to 6 hours, turning
melon occasionally.
Remove plug. Drain all liquid through fine-mesh sieve into small saucepan. Add
remaining 1 cup port and bring to a boil. Reduce liquid to 2/3 cup of syrup.
Cut melon in half and remove seeds. Using a melon baller, scoop out small melon balls
and place in bowl, collecting any of the juices. Add a pinch of salt and a grinding of black
pepper. Stir
Mound melon balls evenly on 6 large flat plates. Drizzle with reduced port. Drape
prosciutto over melon and serve. Pass the pepper mill.
