Did you ever feel the urge to bake cookies but didn't know what ingredients you need to bake cookies? Even Aristoteles knew of some ingredients for baking cookies. Yes that is right baking cookies, or baking biscuits like the British would say has a long history. No need to go to the shop when you have the recipe for baking cookies.... etc. etc.
On the other hand, Google apparently can't distinguish between quality content and auto-generated SEO filler drivel. It has to be auto-generated, right? No one could write that stuff by hand...
Sometimes it is useful for coding, where there is some refactoring done that helps you to understand the "why" of some changes.
But it clearly depends on the video. Many have the 20 useful seconds burrien in 4 minutes of BS.
On the other end of the spectrum, when I look for information about how to assemble a transmission (or similar) I instead find someone who has cut together some short video that doesn't actually contain good shots of the various assembly steps.
You can't copyright the raw list of ingredients, as it is a factual statement with too little creative input (in the list, not the recipe itself!) to get copyright protection.
To stop the recipe blog just being scraped by some recipe site and get zero visitors/impressions for themselves, they have these (at least) "minimally creative" intros that qualify for copyright.
...then the recipe sites just changed to extract the factual non-protected recipe from that, and the arms race escalates. "Whisk the eggs in with a feeling of freedom, and duty to the ancestors" - COPYRIGHT, BABY!
Coca Cola recipe isn’t copyrighted or trademarked. They went the third route “trade secret” and interestingly enough, the exact recipe they use is still secret, despite all the years it’s existed.
(Yes, some have approximated it though if memory serves)
Funny enough, it's just like tickling. You have to know that it's Coke to taste Coke. Drinking another brand that tastes identical to Coke in blind tests is like tickling yourself.
What other brand tastes like Coke? I guarantee I can blind taste identify most (all?) the common US brands of cola.
The specific wording and 'flourish' of recipes is copyrightable, but the actual factual, meaningful content - the one which impacts the 'success' of the recipe - fundamentally can't be restricted by copyright, you can't get an exclusive monopoly to make a particular concoction through copyright law (you can with patent law, but it has other restrictions).
It's similar to copyright on design for e.g. clothing - the arbitrary artistic parts can be protected with copyright, but the functional parts can not be restricted that way.
So if you know how to make Coca Cola and want to do that, copyright law won't protect that. Perhaps patent law might (I'm not certain) but there is no patent on the Coca Cola recipe - and if there was, the recipe would have to be published in the patent application, and it would expire in 20 years, unlike copyright. However, you could not freely say that it's exactly like Coca Cola (trademark laws would restrict that), and it does matter how you got that recipe - trade secrets are protected, and if you got the recipe through illegal means (e.g. breaking&entering, or bribing an employee) then you could have repercussions for that.
internet recipes are designed to be below 40min, if you look at the instructions. but for certain steps, developing the actual flavor would need to be longer - but „customers“ don’t want recipes that take longer.
so all produce a very limited taste range
