Two winters ago, I bought myself an ice cream maker. It cost $50. It has a bowl that needs to stay in the freezer overnight before attempting to use it (trust me, I’ve tried without), and it has a plastic insert that churns the cream into ice cream when the electric motor rotates the bowl around and around. It’s a simple machine, and it’s pretty cheap. And I honestly don’t know why everyone who likes ice cream doesn’t get one!
