My partner recently bought a receipe book that was probably 100% slop, from the recipes themselvea to the images for each dish.
Local bookshops are great, use them or lose them.
Later and you start seeing "Use this new processed wunderfood ingredient substitute!" (70s-00s)
The only solution is to find recipe books that were printed in previous decades.
Which is ironic, given that Google's entire value proposition (to users) was extracting signal from noise...
... and now it's come full A/B-advertising-optimization to being useless at that, when the need is greater than ever.
Imho, Google's greatest failing was missing how its own incentives warped creation of new web content, and failing to account for that strategically -- it turned the web into something it can't itself usefully parse.
