A kettle is a kitchen appliance used for boiling water. It typically consists of a container with a spout and a lid, often made from materials like stainless steel, glass, or plastic. Kettles can be powered by electricity or used on a stovetop. Electric kettles heat water quickly and usually have features like automatic shut-off and temperature control. Kettles are commonly used for making hot beverages such as tea and coffee. They can also be used for cooking tasks, like preparing instant noodles or blanching vegetables. The design and functionality of kettles have evolved, with some models offering advanced features like programmable settings and keep-warm functions.
