You can use pureed fruit or maple syrup to sweeten the yogurt if desired. I’m going to try raspberry puree next!
Place a piece of cheesecloth over a strainer and pour yogurt in the cheesecloth. Fold the cheesecloth over the top of the yogurt and set in the fridge overnight (this step removes the excess moisture from the yogurt to give you a thick, greek-like yogurt consistency). The next day, place the strained yogurt in a mixing bowl and whisk in honey, lemon and vanilla. Pour mixture into an ice cream maker and follow manufacturer’s directions for freezing. Serve.
