RECIPES TO TRY THIS SUMMER:
Ice Cream in a Bag
Ingredients (Per group of 4)
Most foods are made from living or once-living material and all such material is made of cells. Water is one of the few substances that expands on freezing, so if you put something made of cells into a freezer, the water inside them turns to ice and expands, rupturing the cells and damaging other structures. Slow freezing gives large ice crystals time to form. For ice cream, commercial freezing is done rapidly to prevent large ice crystals from forming. Constant churning is also used, as in homemade ice cream and the ice cream made in this activity. This breaks up larger ice crystals as they form. When melted ice cream is put in the freezer, it freezes slowly, allowing large ice crystals to grow and making the ice cream unpleasantly crunchy.
