01 - Place the cubed cantaloupe in a blender and purée until completely smooth, scraping down sides as needed.
02 - In a large bowl, whisk together the heavy cream, sweetened condensed milk, granulated sugar, vanilla extract, and sea salt until fully combined and slightly thickened.
03 - Gently fold the cantaloupe purée into the cream mixture using a spatula until fully incorporated and uniform in color.
04 - Transfer the mixture into serving glasses or bowls. Cover and refrigerate for at least 2 hours to allow flavors to meld and the cream to set properly.
05 - Just before serving, finish each portion with a sprinkle of flaky sea salt, fresh mint leaves, and additional cantaloupe cubes or balls if desired.
