I recently bought an espresso machine. The guy at my local roaster convinced me that instead of using the milk steamer on the machine it would be better to heat milk on the stove or in the microwave, then to use a foamer to make perfect microfoam. I bought the gadget, which has a plastic handle connected to a wire which ends in a spiral loop. I've been heating the milk then using the foamer, but my results are disappointing - I just get a thin layer of foam, and not with the characteristics of microfoam - more like big bubbles. I am thinking that either my technique is bad or I'm just not placing enough milk in the glass. Anybody have experience in this area? Thanks.
