Forget endlessly cranking the handle of an ice-cream maker. After combining the ingredients, each guest can simply shake up his or her own pouch of soft serve -- and it's done in just 5 minutes. Then try more sweet treats in our Best Ice-cream Recipes Gallery.
Combine the sugar, half and half, and vanilla extract in the pint-size bag and seal it tightly.
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.
