1/2 cup milk
1/2 tsp vanilla
1 tbl sugar
4 cups crushed ice
4 tbl salt
2 qt size Ziploc freezer bag
1 gallon size Ziploc freezer bag
1 hand towel or gloves to keep your fingers from freezing

Mix milk, vanilla and sugar together in of one the quart bags. Seal tightly, allowing as little air left inside the bag as possible. Place this bag inside the other quart bag, again leaving as little air left inside as possible.
Place the two bags inside the gallon size bag and fill that bag with ice and then sprinkle sale on top. Again, let the air escape and seal the bag. Wrap the bag in a towel or put on gloves and shake and massage the bag, making sure the ice surrounds the cream mixture. 5-8 minutes is enough for the mixture to freeze into ice cream.

TIPS: freezer bags work best!
