Ice Cream in a Bag -Brenna

1 cup milk
1/2 tsp. vanilla
2-3 Tbsp. sugar (its better with 3!)
dash of salt
3 Tbsp. rock salt
2 cups ice

Mix the ice cream ingredients in a quart size Ziploc bag. Push the air out and seal the quart bag. Double check to make sure it's sealed! Put the quart bag into the gallon size bag, and seal the gallon bag. Then,  knead the bags until the ice cream is ready! You can wrap the bags in a dishtowel while you knead, but I think its more fun to do it without one.
