How to make homemade ice cream in a plastic bag

No ice cream? No problem! You probably have the ingredients at home to whip some up.

You Will Need
Two resealable plastic bags, one gal.-sized and one qt.-sized
1/2 c. reduced-fat or whole milk
1 1/2 to 2 tbsp. of sugar
1/2 tsp. of vanilla extract or 1 tbsp. of cocoa powder
2 trays of ice cubes
6 tbsp. salt
Waterproof winter gloves
Chocolate or butterscotch chips
Flavored syrups
Flavoring extracts

Step 1: Put ingredients in smaller bag
Put the milk and sugar in the quart-sized bag and seal it. For vanilla ice cream, add vanilla extract; for chocolate ice cream, add cocoa powder. Throw in a quarter of a cup of chocolate or butterscotch chips if you like.
Experiment with other varieties by using ½ to 1 tsp. of flavored syrups like strawberry or caramel or extracts like lemon or almond.

Step 2: Make an ice bag
Put the ice and the salt in the gallon-sized bag.

Step 3: Put small bag inside big one
Put the smaller bag inside the bigger bag and seal it.

Step 4: Shake it
Shake the larger bag vigorously for seven to 10 minutes.
Wear winter gloves while you shake; the bag is cold!

Step 5: Enjoy
Remove the small bag, which now contains ice cream. Snip a hole in the corner of the bag and squeeze it into a dish. Makes one serving.

I'd love to try this especially when it's very hot. No need to buy outside! :)
