A slow cooker is a kitchen appliance designed for cooking food at low temperatures over an extended period. It typically consists of a ceramic or metal pot that sits inside a heating element. This method allows flavors to develop and ingredients to become tender without constant supervision. Slow cookers are versatile and can be used for a variety of dishes, including soups, stews, and casseroles. They are energy-efficient and can be left unattended, making them convenient for busy individuals. Many models come with programmable settings, allowing users to set cooking times and temperatures according to their needs.
