This is a fun, fast treat that was a pleaser with the kids and I have to say not a bad quick icecream.
In a pint size ziplock bag place
1 Tbsp sugar
1/2 cup milk or half and half
1/4 tsp vanilla
Revmove as much air as possible and place this bag into a gallon size ziplock bag filled 3/4 of bag with ice and add to this 6 Tbsp rock salt. Again remove as much air as possible and seal bag. Take a towel and massage the ice around the smaller bag which mixes the ingredients and ensures even freezing. This takes about 5 minutes and your hands will appreciate the towel so they don't freeze too. I recommend crushing fruit also and don't put in as much as I did.
If you want flavored icecream add your choice after the icecream has thickened and is ready to serve.
