It's not entirely clear why cheese is seen to have magical properties. It might be to do with the fact it's made from milk, a powerful substance in itself, with the ability to give life and strength to the young. It might also be because the process by which cheese is made is a little bit magical. As I was scrolling through Twitter recently, a viral tweet caught my attention. It was an image from a book of spells claiming that: "You may fascinate a woman by giving her a piece of cheese." The spell comes from Kathryn Paulsen's 1971 book, The Complete Book of Magic and Witchcraft – and, while proffering a lump of cheddar may seem like an unusual way of attracting a possible mate, Paulsen's book draws on a long history of magic. It's a history that has quite a lot of cheese in it.
