CHEF'S TIP: If you don't have a Nina CREAMi, prepare the custard base as directed. Pour through a mesh strainer, into an air-tight storage container. Leave uncovered to cool to room temperature. Transfer base to refrigerator; chill 3-4 hours, or overnight. When ready to make, transfer base to ice cream maker of your choice, along with the mashed bananas. Churn ice cream following manufacturer's instructions.
If you don't have an ice cream maker, place the ice cream mixture in a quart-size plastic zip-top bag, squeezing out as much air as possible. Seal tightly. Place this bag inside a second quart-sized plastic zip-top bag. Squeeze out as much air as possible and seal tightly. Put the double-bagged ice cream base inside a gallon-size zip-top bag and fill with approximately 4 cups crushed ice. Sprinkle the ice with 4 tablespoons coarse salt. Press out as much air from this bag as possible and seal tightly. Wrap the bag in a towel or don your favorite pair of gloves. Shake the bag vigorously, massaging the base as needed to ensure the ice is surrounding the ice cream mixture at all times. Shake ice cream base 5 - 8 minutes, or until the ice cream is frozen. Remember, the more vigorously you shake, the smoother your ice cream will be.
