What I'm saying is that the "recipe" part of a recipe website is a
commodity – there
is no "authoritative" source for a given recipe, unless that recipe is too niche in appeal to end up widely disseminated. This video (
https://www.youtube.com/watch?v=SsNLzyqqINw) has a pretty good coverage of the topic.
Compare and contrast: phone-number directory listings. Who should Google cite as the authoritative source for lists of name-to-phone number associations? Nobody. All the lists are copying from each-other, curating and correcting the data taken from one-another, gathering their own original data for additions, and everything in between. Every portal overlaps every other portal, but mostly has the same stuff.
Compare and contrast, in the physical world: printings of public-domain literature. If Google indexed bookstores, which printing by which publisher would you want them to rank first on a search for e.g. Pride and Prejudice?
