The book is the context! It was published, it has a presumably influential vetted author.
Maybe I am coming off too flippant. I'm just trying to say there's a spectrum between fluff and context. If the AI's literally just gave us answers and list of recipes, it wouldn't be as useful as with the context backing up where it came from, why this list, and so on.
Perhaps it also depends on one's approach to cooking. I often read recipes not because I intend to follow them, but to understand the range of variation in the dish before I make my own version. "Somebody liked this enough to bother writing it up" is enough context for that use.
