Indio32 - the way to do this is to add an eBook or Kindle bookmark to all your eBooks. Then when searching for recipes on your Bookshelf, apply that filter in the right column under My Bookmarks "Look in Books". You will then only see recipes in your search that are from those books. You can use Book bookmarks in the same way if you have cookbooks in two different locations, or you just want to searchh in your favorite books.
