I can see the attraction of having recipes from a book listed in random order. Imagine repeating what the late Julie Powell did cooking through Julia Child's Mastering the Art of Frnech Cooking (1961 edition) it would be boring to spend the first few weeks cooking nothing but soups and the following weeks cooking nothing but sauces. Boring both for the cook and those being served the food. Having the recipes presented in a random order might prove beneficial to the project.
I find myself in a similar situation at the moment as I plan a project inspired in part by Julie Powell — Julie and Julia is a favourite film of mine —, the Bread Baker's Apprentice Challenge —baking all the breads in Peter Reinhart's Bread Baker's Apprentice —, and Instagrammer Chubbeekitchen who bakes random receipe from one book over two months. My project is intended to take me from being a pathetic baker to a confident and successful home baker in one year by using One Book for One Topic — be that bread, pies (sweet and savoury), patisserie, cakes, cake decoration, biscuits and cookies, — over One Year ( OBOTOY). An education in baking without the expense of travelling to Paris to attend Le Cordon Bleu, Lenôtre or Ferrandi.
However most of the books at my disposal have sections on specific subtopics. For example bread books tend to have a section on sourdough and much as I love sourdough and could eat nothing but that type of bread other members of my family only tolerate it occasionally. They would hate to have nothing bu sourdough breads for weeks. Hence getting the recipes/formulaes in random order could overcome their objections to a type of bread they do not like.
Perhaps what I want is more a shuffle a la iPod Classic rather than Spotify's irritating function of selecting random tracks after a playlist has finished.
