Cut
the melons in half horizontally. Remove the seeds.
Use the melon bailer to remove the flesh from each
half and place the balls in a large bowl.
Remove all
the remaining flesh on the inside of the skins. Pour
the Port over the melon balls and
mix well.
Refrigerate for at least 2 hours.
Use
an ice crusher or put the ice cubes in a tea towel
and crush well with a meat tenderizer. Place the
crushed ice in individual bowls.
Place the empty melon halves on top of the ice and
fill with the melon balls.
Pour the remaining
marinade over each melon half. Serve immediately.
