Ice cream machines are appliances designed to make ice cream at home. They come in various types, including manual and electric models. Most machines mix ingredients like cream, sugar, and flavorings, then freeze the mixture while churning it to create a smooth texture. These machines can vary in size and capacity, catering to different needs. Some popular brands include Cuisinart and Nostalgia, which offer user-friendly options for beginners. Ice cream machines can also be used to create other frozen desserts, such as sorbet and frozen yogurt, making them versatile kitchen tools.
