Once the mixture has thickened remove from he heat and put in the frig to cool down completely about 2 hours. Once it has cooled pour into ice cream maker and process according to directions on the machine. I churn it about 20 minutes and then pour in any fruit if adding and churn until it’s the way I like it, about 10 to 15 more minutes. Store in the freezer and allow to freeze for about a 1 hour or over night before serving.
