According to https://copyrightalliance.org/are-recipes-cookbooks-protecte...:

    Recipes can be protected under copyright law if they are accompanied by “substantial literary expression.” This expression can be an explanation or detailed directions, which is likely why food and recipe bloggers often share stories and personal anecdotes alongside a recipe’s ingredients.

So besides SEO, there's this thing where the recipe itself is basically defenseless against someone stealing it and calling it theirs but the sum of the fluff around it plus the recipe on the other hand can be copyrighted and enjoys all the protections afforded to these kinds of things. So, if say, Jamie Oliver likes your recipe and puts it in a book passing it as his, you can now legally tell him to stop doing that because of said fluff.

However (from your source),

     Even if the description of the recipe is sufficiently creative and copyrightable, the copyright will not cover the recipe’s ingredient list, the underlying process for making the dish, or the resulting dish itself, which are all facts. It will only protect the expression of those facts. That means that someone can express the recipe in a different way — with different expression — and not infringe the recipe creator’s copyright.

So they can still put your recipe in a Jamie Oliver cookbook, they just have to put it in their own words as opposed to copy pasting it verbatim.

I don't think that's the case. He'd only get in trouble if he reproduced the "substantial literary expression." The actual list of ingredients and step-by-step procedure aren't copyrightable.
