One of my favorite cooking videos is "Pastry Chef Attempts to Make Gourmet Kit Kats" - https://www.youtube.com/watch?v=4nqJiBRNQuw

It's a perfect example of hacking without a computer. There is a whole series of these videos trying to recreate mass produced junk food in a test kitchen, and it's incredible how difficult it can be for even a very experienced chef. It makes you wonder how these products were ever created.

There used to be a rule in chocolate bar design -- always have at least one secret step which is hard to reproduce. Those trade secrets were how you stopped people producing clones of your product. Nowadays you can try for a trademark instead.
