Here are some useful tips:
1) Read and follow your ice cream maker or ice cream maker attachment
directions.
2) Do not overfill your ice cream maker. If necessary, make two batches.
3) Make sure your ice cream base (or in this case, custard) is completely chilled.
4) Add your mix-ins (nuts, fruits, etc.) just before the ice cream is done churning.
5) Leave your ice cream maker attachment in the freezer in a bag so you can make your ice cream any time you like!
6) Your custard base is the building block for a perfect ice cream. Your custard is cooked when it's thick enough that it covers the back of a spoon or when it has reached a temperature of about 170 degrees.
7) Take your ice cream out of the freezer at least 10-15 minutes and transfer the container to your fridge before serving.
