materials

  • ½ cup of heavy cream or half and half 
  • 1 tablespoon of sugar 
  • ¼ teaspoon of vanilla extract
  • 2 quart-size plastic bags
  • Salt
  • 5 or more cups of ice
  • 1 gallon-size plastic bags
  • towel or gloves

directions

  1. 1. Measure the cream, sugar, and vanilla extract into the quart-size bag. Remove the extra air and zip it up tightly.
  1. 2. Place the ice cream bag in a second quart-size bag to reduce the risk of spills. Zip up tightly.
  1. 3. Fill the gallon-size bag with ice. Add the salt. Put the sealed smaller bags inside. Now zip up the larger bag.
  1. 4. Shake and shake the bags to make ice cream! It will take about 5 to 10 minutes until the cream hardens.
  1. 5. Take the smaller bag out of the larger one. Eat the ice cream right out of the bag!
