I’ve followed him for years now and Andre is right. Raphael has no preparation in cooking or in anything tbh. He was lucky enough that his content blew up enough for him to make a good profit out of it. He does uses many words that are common in the cooking industry, but I believe he knows them because he learned it from tiktok or other youtube videos. Probably he doesn’t quite understand some of the words he uses but uses them correctly because he’s repeating them in the same context as other cc use them in their own videos. He did also published a cooking book, but some years ago he said on video that they just hire him to put his face on it to sell as much copies as possible. He also said that the book is awful and critiqued some of the recipes because of how generic they are. Don’t get me wrong, I like the guy. I think he’s good looking and very funny because of how silly he is, but his success comes from that and not because he is a chef or something like that.
