For me, it would probably have to be my Bialetti moka pot and Dualit toaster. I make a pot of coffee and toast almost every morning. I also hope to replace my old pans with a cast iron one soon, and I look forward to using that a lot.
I’ve heard that too…of course, I can’t compare to 240V but it takes me probably 2-3 minutes to boil about 2 cups of water and probably 5-6 for a full kettle at a rolling boil (rough estimate from memory). It’s not much faster than the stove but theres no wasted heat, and no hot pan sitting on a burner after I’m done. Another theory I’ve heard is that in the US people opt for a drip coffee maker instead of a kettle (for their one spot on the counter? Why not both?), since we don’t drink tea that often.
We drink coffee, but prefer an electric kettle for water and then use the pour over method for individual cups or french presses if we need more than a cup at a time in a hurry. Less waste this way and allows for tea and coffee when hubs and I want it. My in laws visit every time and rave how much fresher the coffee is made in small batches, fresh ground, but then looks at us as if we are nuts for not having a standard coffee maker and keeping the electric kettle instead.
