Aubrey compares this, writing "I did imagine nothing to have been in this but mere wantonness of youth ... but I find in Buchardus's book Methodus Confitendi ... one of the articles of interrogating a young woman is, if she did ever subjugere panem clunibus, and then bake it, and give it to the one she loved to eat". From this he decides "I find it to be a relic of natural magic, an unlawful philtrum" (i.e. aphrodisiac or love charm).
