it’s closer to a cappuccino, really. If you can make good espresso (I mean, really good espresso) and are an old hand at the foamer, sure. Yes, it’s a simple thing, like olive oil and bread, with a wide range of possible outcomes that still fit the general description.
Sadly I don’t know where to look for it right now.
But remember that kid on /r/Ireland who ranked all the hot chocolates in Galway? I hope he shows up here sometime.
