Ingredients:

  • 1 cup half-and-half
  • 2 tbsp granulated sugar
  • ½ tsp pure vanilla extract
  • 4 cups ice cubes
  • ½ cup kosher salt

Instructions:

  1. Pour the half-and-half, granulated sugar, and vanilla extract into a quart-sized freezer bag. Squeeze out as much air as possible and seal the bag tightly.
  2. Fill a gallon-sized freezer bag halfway with ice cubes and pour the kosher salt over the ice.
  3. Place the sealed quart bag inside the gallon bag, nesting it securely among the ice, and seal the larger bag firmly.
  4. Using winter gloves or a thick kitchen towel for protection, shake, roll, and massage the bag vigorously for 7–10 minutes until the mixture reaches a thick, soft-serve consistency.
