Kettle: “a container or device in which water is boiled, having a lid, a spout and handle”.
I recently received a high tech kettle as a birthday present. It’s great. I can now boil the water at the correct temperature for all my teas. No longer do I have to take the lid off the kettle to wait until I think it’s cooled to 80 degrees. White, yellow, green, black.. all tasting perfect.
