I've had an electric kettle for 40 years - everyone in the UK has one. When I was a child, my mother used to put a kettle on the gas hob to heat. When my husband went on a business trip to the US in the 1980s, he phoned me from the apartment he was staying at and said, 'There is no kettle, how on earth am I supposed to make tea.' We always have a kettle and a teapot in this country. How can you manage without them!
The modern ones boil just the right amount of water and shut off automatically. The old ones that you put on the gas hob had a whistle and would sing when the water was boiling. That was to tell you to take it off. Do you know the old rhyme:
Polly put the kettle on, Polly put the kettle on, Polly put the kettle on we'll have some tea.
