Making espresso at home does entail a fair amount of accoutrements. Some are absolutely necessary, like espresso machine cleaner and a good tamper; some less so, like a dedicated frothing pitcher. Can you use a jar or old can to steam milk? Probably. Do you want to? Probably not. We care to draw the line at tamping mats, which we don't find useful at all.
If you are going to go all out, you might as well do it up. We don't carry fancy or froo-froo espresso accessories; just basic, useful supplies.
