It is important to keep in mind that a recipe is only a roadmap to help you along. Your knowledge, understanding of the different properties of food, experience in baking, and sweat are what makes your formula yours. You can share the exact recipe to 20 people and you will get 20 different products. No one can take away your experience in baking. A very well known chef once told me that if one is not willing to share a recipe, it must be because you don't have enough skill or experience to stand out from it. Share and share alike. By the way, I love macarrons. Would you share that recipe? Chris
