A month ago my glass coffee pot broke from my electric coffee maker. I thought about purchasing a new one, but I am trying to do more with less. I like to maximize my space on the counters. The next morning in desperation for coffee, I tried making coffee in my cast iron tea kettle, and it was very good! With a little experimentation, I discovered that the grounds sink to the bottom when the water is left to come to a rolling boil, taken off the heat immediately, and then left to sit for a minute or two. I don't even need to strain the grounds. The tea pot is well seasoned, so clean up is very easy, just a rinse and quick scrub.
I cook two cups of coffee with half a pot of water and two heaping spoons of grounds. So easy! And I've got more counter space now, not to mention no glass coffee pot and coffee maker to clean.
