Oh, now I see! You don’t understand that a microwave can boil water, you think it can only warm it up a little. Thank you for clearing up my confusion.
Have some class!
Whenever I hear Europeans accuse Americans of being arrogant, I can only laugh. Feeling superior about something like how you boil water is hilarious.
Most people would just put water in the mug (ceramic/microwave-safe of course) that they’re going to make the tea in and microwave it until it boils or bubbles just short of a rolling boil, which takes 2 or 3 minutes, depending on the microwave’s power–you’d learn the time yours takes and set the timer for that. At that point I don’t see the difference between that vs. if you poured it into the cup from the kettle. Either way you now have a cup full of boiling-hot water to steep your tea in. No, it won’t spill over if you don’t fill it all the way up to the brim.
