...there is no plausible endowment of prior knowledge which could make this book not be really, really badly written. It reads like a GPT-4 content farm that produces long anecdotes about kitchen recipes followed by eventually coughing a recipe found verbatim on some more concise website, but without explaining in the slightest how to "slice garlic" or how thinly to slice it, if you don't already know what that means.
As for the content, it's about trying to produce intangible magical tentacles that will produce slight tingles, as might possibly be an amusing diversion if bed if the victim was already really, really turned on.
