And no, the microwave is not a valid option.
Yes, this is one of the more bizarre cultural differences. I have seen people from the UK object strongly to Microwaving water.
Microwaving food definitely affects the way it tastes because it heats unevenly. Cooking foods different ways affects the outer browning, moisture levels, etc.
Heating water in a kettle on the stove, an electric kettle, a sauce pan, or a microwave doesn’t change the water! If you don’t want to seep tea in boiling water, then let it cool slightly first.
Lots of comments on superheating, mostly to the parent comment, but I’ll put a response here.
You can avoid superheating by putting a reasonable time on the microwave based on the amount of water you’re heating. Especially for something you do again and again, you should be able to quickly get experience with this.
To avoid the uneven heating just turn down the microwave power! No one does this and everyone complains about uneven heating! I get great reheating results from my microwave just by turning down the power and running it for longer.
This is how microwaves used to work decades ago when they were lower power by design. Over time the microwave power arms race resulted in them getting much too powerful for even reheating.
I live in the US and I strongly object to microwaving water. But I am also /really/ into tea so I avoid tea bags as much as possible.
Part of the cultural difference is that US is largely 110 and the UK is 220. It’s faster and easier to use an electric kettle. In the US, the microwave heats up the water “faster” vs the stove or an electric kettle
