Ingredients:
- 1 cup half-and-half
- 2 tablespoons granulated white sugar
- 1/2 teaspoon pure vanilla extract
- 1 pinch fine sea salt
- 3 cups ice
- 1/3 cup rock salt
Instructions:
- In the small quart-sized resealable bag, combine the half-and-half, sugar, vanilla extract, and pinch of salt. Squeeze out excess air and seal the bag tightly.
- Fill the large gallon-sized resealable bag with the ice and rock salt. Place the sealed cream bag into the center of the ice mixture and seal the large bag securely.
- Wrap the gallon bag in a thick kitchen towel or wear gloves to protect hands from the sub-zero brine. Shake the bag vigorously for 7 to 10 minutes until the liquid base has solidified into a firm ice cream consistency.
