Remember making butter in Girl Scouts? Everyone passed around the jar of cream and gave it a good shake. After a few rounds, the cream had magically turned to butter.
Here is a similar feat that not only yields dessert but exercise for the kids—ice cream in a bag. Here’s how it works. Place 3 tablespoons sugar, 1 cup light cream (half and half) and ½ teaspoon vanilla in a quart-size heavy zip-top plastic bag and seal. Place that bag in a gallon size heavy zip-top bag. Layer ice and rock salt in the gallon bag and seal. Toss the bag back and forth for approximately 10 minutes, and voila, it’s ice cream. Serves 2 hot kids (or adults).
