Chef's notes
As this appetizer (though often served as a dessert in Spain) is only two ingredients, make sure they are both the best you can find.
*For the melon: If it is ripe, all you have to do is press lightly near the stem end. If the rind gives a bit, the melon is ready. Also, smell it, when it's perfectly ripe, you can smell it's wonderful aroma.
**For the prosciutto: It should be thin enough that you can almost see through it, that way it almost melts in your mouth. Have the butcher slice it for you.
Keep the prosciutto in the refrigerator until you are ready to assemble the platter.
