Penguin biscuits have been around since 1932. They originate from Glasgow, but nowadays they’re manufactured in Stockport in England. After all this time, they’ve become ubiquitous, an ever-present component of every teatime. It’s hard to overstate the popularity of the Penguin – McVitie’s have claimed in the past that they make 40,000 biscuits a minute. The everyday familiarity of the Penguin means it’s a great standard against which all other chocolate biscuits can be judged – if it’s more luxurious than a Penguin, it’s definitely fancy.
