Ok, Brits. Educate me. What's the benefit of a tea kettle over heating water in the mug you'll drink it out of in the microwave? (Assuming you're making one cup of tea.)
The "slight difference" is you need to clean out your fucking microwave. 🗣️
I've made tea on gas, electric, & even mf induction stovetops, over an open flame, using an electric kettle and in a microwave.
There's 0 difference. The only thing that matters is getting the water to boiling temperature, which all can.
