To make lemon frozen yogurt, first whisk all ingredients in a large measuring cup. If using an ice cream maker, simply pour the mixture into your chilled machine and churn according to the manufacturer's instructions. Or if you do not have an ice cream machine, pour the mixture into ice cube trays and freeze. Thaw just enough for a blender or food processor to easily handle, then blend until smooth. Serve and enjoy. See above for tips and troubleshooting.View Nutrition Facts
