I have read two anecdotes online, but would it be possible to order an outlet or 'socket' from the UK Amazon, along w/ a kettle, and wire it into its own dedicated 20A 220v US circuit?
Electrical code becomes an issue; afaik the NEC doesn't have provision for UK plugs, and you'd have to wire it up with both legs of your residential service. That's a layer cake of failed inspection. You may not care, but any future home buyer might, and your insurance company very well may too, should your house ever burn.
