You can make single servings the same way that those "hand crank" manual icecream makers work. I don''t have the recipee, but just use the normal ingredients, mix those in a small ziplock bag and then place that ziplock plastic bag in a larger one filled with ice and salt (make sure the small one is sealed or you will have some salty icecream). Then just sort of message the ice around the bag. It takes some work (5-10 minutes), but you will burn off the calories that you are about to consume. My engineering community serice team made the icecream with some kids on a Discovering Engineering Day at our University (they loved it).
