Cover the moulds with ham (as you can see from the shape of the fingerfood, they are small). Then, cut the ham to cover the moulds well. In a dish beat an egg with salt, pepper and Parmigiano Reggiano and add the melon into cubes and the remaining ham. Put everything into the moulds and insert the ice cream sticks. Place in the oven for approx. 10 minutes at 180 degrees. Leave to cool and remove from the moulds.
