I don’t own an ice cream machine. I just don’t eat ice cream much. But I had several ripe bananas that I didn’t want to wait to ripen more for banana bread. I decided to buy some good vanilla ice cream and add the mashed bananas and refreeze, stirring periodically to get a smoother consistency. It worked really well, and the ice cream tasted very much like banana ice cream. It was well worth the little bit of effort to get to the right taste. I’m thinking of trying this method with other add-ins. Give it a try. Unless you eat a lot of ice cream, an ice cream machine is just one more appliance to take up space, and that you have to move if you move. And you can never get that kind of ice cream you want when you are having just that particular craving.
