1. Prepare the custard base as directed in the recipe (including chill time in the refrigerator).
2. Remove custard from the refrigerator and stir with a rubber spatula. Transfer the mixture to a deep freezer-safe bowl or container and place in the freezer for 45 minutes.
3. As it starts to freezer near the edges, remove from the freezer and stir vigorously with a fork or whisk, being sure to break up any frozen sections. Return it to the freezer.
4. Continue to check every 30 minutes, stirring vigorously as it’s freezing. It is estimated that it will take 2-3 hours for the ice cream to sufficiently frozen and ready.
