Once while in Italy, I saw people snacking on platters of prosciutto and cantaloupe, and the memory inspired this drink years later. People clamor for it at the beginning of summer, but I like to wait until the cantaloupes are super sweet and juicy.

Add the liquid ingredients to a Boston tin half full of ice, swirl for a bit, and then strain into chilled martini glass. Lay skewer (see below for instructions) across the top of glass.
Roll pieces up in a cone shape, stick the pointy end in the olive, and try to have the extra ham flare out in a cool way. When skewering olives, pierce near the open end, so that the bottoms hang down in the drink and the flared prosciutto points upward.
