Completely unrelated to AI, I buy and always bought recipe books in second hand bookstores. It has this vintage vibe, and not everything has to be kale. Downside is that some ingredients aren't easily reachable, but it doesn't happen that often.
Totally related to AI. You're gonna be able to spot slop whilst browsing.
Local bookshops are great, use them or lose them.
My favorite are 50s and 60s recipe books. They use modern ingredients where appropriate, but mostly basic ingredients.
Later and you start seeing "Use this new processed wunderfood ingredient substitute!" (70s-00s)
