I just bought a Melitta Express Kettle. I was amazed at how quick the water boiled when i tried it out. It did not come with any instructions so it was pretty simple on how to use. I wanted to use it to make tea...not hot tea one cup at a time....but to boil and steep the bags for my ice tea. Is it ok to do this and is there anything you can heat in it? I made my first pot of tea in it, let if come to a boil, then let it steep for about 30 minutes and when I turned it back on to get tea hot enough to melt the sugar in the tea pitcher, It boiled over and was only on for about 2 minutes. Would love some advice on my new little gadget.
