This is another fun treat we made when my sister and her kids were staying with us. The ice cream was definitely soft serve consistency, but it was super yummy, especially when we crushed some Oreos on top. Just be careful when you open the inner bag that you don't get any salt on your ice cream.
1 tablespoon sugar
1/2 cup milk or half & half
1/4 teaspoon vanilla
6 tablespoons rock salt (I just used Kosher salt)
1 pint-size plastic food storage bag (e.g., Ziploc)
1 gallon-size plastic food storage bag
How to make it:
Fill the large bag half full of ice, and add the rock salt. Seal the bag.
Put milk, vanilla, and sugar into the small bag, and seal it.
Place the small bag inside the large one, and seal it again carefully.
Shake until the mixture is ice cream, which takes about 5 minutes.
Wipe off the top of the small bag, then open it carefully. Enjoy!
