I would love this feature! Even if the recipe were of no interest to me on that day, it might be later, or it would most likely cause me to at least open up the book and see what other treasures it held. Technically, this might be difficult, but it would be an especially cool feature if the recipe happened to be seasonally appropriate -- for example, a recipe using peaches or tomatoes or corn in August, an asparagus recipe in spring, a hearty stew or soup in winter, etc.
