such interesting topic about sharing recipes. personally, i do share all recipes, and feel that you need more than a recipe to make a great product. even with cake bible recipes, that are written and explained in well detail, one get results slightly different than others. if you have a recipe you mastered and are well welcomed by your people, it is very unlikely to be duplicated by anyone trying the same recipe… unless they have the exact same equipment, baking conditions, environment, and ingredients. i even go farther in sharing my recipes by inviting people over to watch or by going to their homes.
but i would never share a recipe that i got from a book. book writers get paid very little for what they do, and books are much more affordable nowadays, so i refer them to buy the book!
