Brandi Milloy’s tip: If you don’t have room in your freezer to store a handful of trays, try this hack for turning your kitchen into a rolled ice cream shop. Purchase Dry ice pellets, which are essentially crushed dry ice, available at most grocery stores—just be sure to call ahead. Using temperature-safe gloves and extreme caution, pour the dry ice into a baking sheet, filling the pan. Then place your rolled ice cream tray on top. The dry ice will keep your entire tray cold, making rolling the ice cream much easier. If the dry ice causes your ice cream to harden too much, take the tray off the dry ice and try again. It takes practice and rhythm, but once you get the hang of it, you’ll be a pro at making rolled ice cream at home.
