Ice cubes (enough to fill each gallon-size bag about half full)
- Combine the sugar, half and half, and vanilla extract in the pint-size bag and seal it tightly. (I double bagged ours, because I’m paranoid like that!).
- Place the salt and ice in the gallon-size bag, then place the sealed smaller bag inside as well. Seal the larger bag. Now shake the bags until the mixture hardens (about 5 minutes). Feel the small bag to determine when it’s done.
- Take the smaller bag out of the larger one, add mix-ins, and eat the ice cream right out of the bag. Easy cleanup too! Serves 1
