01 - Place the cubed cantaloupe in a blender and process until completely smooth, about 30-45 seconds. Set aside.
02 - In a large mixing bowl, whisk together the heavy cream, sweetened condensed milk, granulated sugar, vanilla extract, and sea salt until the sugar dissolves and the mixture is well combined.
03 - Gently fold the cantaloupe purée into the cream mixture using a rubber spatula until fully incorporated and no streaks remain.
04 - Pour the mixture into individual serving glasses or bowls. Cover tightly with plastic wrap and refrigerate for at least 2 hours to allow flavors to meld and the cream to set properly.
05 - Remove from refrigerator and garnish each portion with a sprinkle of flaky sea salt, fresh mint leaves, and additional cantaloupe cubes or balls if desired. Serve immediately while chilled.
