Many people have fond childhood memories of using the hand crank to make ice cream. Today, it might be a matter of convenience to use the electric motor instead! Just remember, if you choose to use the hand crank instead of the electric motor, you will have to turn the crank at a steady, even pace for over 30 minutes! What is the benefit of the hand crank? When the ice cream starts to harden, the electric motor has a safety feature to automatically shut off. If you would like your ice cream a little firmer, without placing it in the freezer, just attach the hand crank and turn for another 10 minutes or so. It is the freezing action that makes it thicker during this time, as the rock salt, ice and brine continue to freeze the ice cream. The ice cream will taste the same whether you choose hand crank or electric.
