  • 3-7 cups of ice

  2. Place the ice, salt and cream-filled bag into the larger bag and seal.  
  3. Vigorously shake the large bag over a sink for approximately 5 minutes. Stop when the cream has started to freeze and turn into a solid.  
  4. Remove the small bag and quickly rinse off the salt solution with cold water.

The Science Behind the Homemade Ice Cream  

Ice cream is an emulsion, or a mixture of two liquids (water and fats) which do not normally mix together. To make ice cream, the milk or cream mixture needs to change its state from a liquid to a solid. If the mixture was simply placed straight into the freezer, the water component would freeze first, forming large, crunchy ice crystals. Ice cream tastes better when it is creamy rather than crunchy, so the goal in ice cream making is to create the smallest ice crystals possible. By vigorously shaking the bag, any large ice crystals that may be forming are broken up into smaller crystals, resulting in a smooth and creamy 57ec5944ffc7bdc0f5e5c6221731f6e2.jpgice cream. The freezing point of ice is lowered by the addition of salt, so it starts to melt. As this ice melts it draws heat energy from its surroundings - including the cream mixture enclosed in the smaller bag - cooling it enough to cause the liquid cream emulsion to freeze, changing it from a liquid to a solid and forming ice cream.
