Even regular cookbooks these days will have a bit of fluff before the recipe for this purpose. Though in a cookbook pictures of food also serve this purpose.
I don't mind that so much because it's easy to skip the fluff - you can find the ingredients and method in under a second since no scrolling is involved
I also wouldn't be surprised if the fluff is there because it was originally written for web and chanced upon finding a publisher
