Its both, but it is also more SEO than copyright. Because yes, that theoretically protects you if someone steals the entire page (not really but let’s pretend it does). But stripping the actual recipe steps out is trivial. at which point we are back to “Can you really copyright adding 420 grams of flour and then mixing it?”

Whereas the giant blog post? If you talk about how your grandmother made this for you on cold November days, you now will show up if someone searches “recipe my grandma made” or “November dish” and so forth.
