Where the recipe actually lives in a cooking video
A cooking TikTok almost never puts the whole recipe in one place. The ingredients get said out loud while the food goes into the pan. A quantity might flash on screen for a second or two, usually as a subtitle burned into the footage. None of that is text TikTok can search, and most of it never makes it into the caption either.
That is the actual problem. The recipe is not hidden somewhere you have not checked yet. It was spoken and shown, not written, so nothing about the video is easy to copy and paste.
