Ice Cream In A Bag (From Science Class)

Ice Cream In A Bag


1 cup half and half or cream (I preferred half and half. Cream sometimes leaves a greasy film feeling on my tongue).

1 cup milk

1 tsp vanilla

1/3 cup sugar
      

Fill big ziplock bag ½ full of ice. Add in 1/4-1/2 cup of salt. I have used both rock salt and table salt before. Rock salt is best, but table salt also works...you just might need to add more or shake longer.  Fill a smaller ziplock bag with half and half, milk, vanilla, and sugar. *I have made this ice cream with only skim milk before. It works if it's all you have on hand, but it's more ice-crystally the less fat you use.* Seal the zipper part of the bag with tape (duct tape works really well).  Put smaller bag inside bigger bag. Then fill the big bag up the rest o the way with ice and add 1/4-1/2 cup more salt.  Seal with tape and mix up.

The above picture shows only half of this recipe. 

We did not have any big bags, so I could not make very much.

*Be sure to seal the small bag very tightly.  You don’t want salt water to get in.  Also, squeeze all the air out before sealing.


*It's fun to wrap newspaper around the bags with tape and play catch to mix up the ice cream. You want to constantly shake the bags until the ice cream is frozen. This takes about 10-15 minutes, but freezing time seems to vary based on how much ice and salt you add, how much you mix it, and how hot it is. Just squeeze the bad when you think it might be ready to judge the hardness of the ice cream. If it's not frozen enough, keep shaking.

*When you are ready to eat, wash the inside bag off a little with cold water so that salt water does not get in your ice cream. Then cut one of the corners of the bag off with scissors, push the ice cream out through the hole, and enjoy!

Used this when we went camping with the extended family. Very fun! Also useful for when kids are bored in the summertime.


Husband's Reaction:"This is great! It takes like a rootbeer float!" (Not sure how much it really tastes like rootbeer, but the consistency is similar to ice cream in a rootbeer float.)
