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.
