I haven’t seen these around for a few years.They are a small, 1 to 3 cup stainless steel and brass (or other golden alloy ) and are like a tiny pressure cooker. They look a bit like an hour glass in shape, maybe all of 6 inches high. What do you call these, and do they still make them ?
Anon-a-MISS > the closest to the design I have found is the Moka expresso maker. It seems to be based on the same principle but the one I used, many years ago, was smaller and silver and gold in colour. Really made great coffee and was fun to use though I forgot how to use one.

I do not drink coffee and don’t want recipes for using espresso in any way, shape, or form. Surely there has to be some cool use for an espresso machine besides making espresso or hot water? I can make hot water for oatmeal or tea in the micro. If I’m going to keep this machine around, it needs to fulfill a purpose. Is there, perhaps, some practical use for its parts?
