You collect the pieces to can buy upgrades, cosmetic changes, and real-life recipes. It has story relevance, but I don't feel like reading this game’s lore. Basically, this big buffalo dude wants to buy a recipe, but then the evil chef dude steals the book and the three main Launchadores severely beat him. The book gets sent to hell and you have to retrieve the pages one by one. However, there’s a limit so you need to time travel using black magic or something but you can only take half of them with you so it gets exponentially worse and then you unlock the juicy beast logo as a playable character. Also, the story has no end for some reason.
