If you do not have an ice cream maker, you can churn this chocolate ice cream recipe by hand. It's just a lot more work! Here's how: Once the ice cream base is made, put it in a freezer-friendly container and put it in the freezer.  After 1 hour, check the ice cream. If is has started to freeze, use a hand-held mixer (or a whisk or spatula) to beat it vigorously.  Continue to mix the mixture with a mixer or by hand every 30 minutes until it is frozen. This should take about 3-6 hours.
