It isn’t hard to figure out these recipes and produce a product that tastes identical. There are several colas that taste exactly like Coke and could easily fool consumers. As far as KFC goes, when I was a kid a KFC manager gave my mom the recipe, as it was not really guarded at the time. She made it at home and it was exactly the same.
The fact that these recipes are technically “secret” is just a marketing tool. It enables the companies to claim that everything else is an inferior knock off, regardless of how correct a copy it is.
