This is an easy ice cream recipe that uses a milk carton as a mold and only two ingredients: heavy cream and condensed milk. Wash the inside of the milk carton, wipe off the moisture thoroughly, and add the well-chilled heavy cream and condensed milk. Close the lid and shake well until the contents become thick, then freeze for at least 3 hours until firm. Once frozen, cut open the milk carton with scissors, remove the ice cream, cut it into your desired thickness, and insert an ice cream stick to finish. It features a fluffy and smooth texture and a rich milky flavor, and melts in your mouth. It's an easy and fun recipe, so please try it as a snack.
