I bought Baking by Flavor about three weeks ago and have tried 2 recipes from it. I did not exactly follow the directions though because upon reading it I realize that you have to prepare ingredients in advance. First of all, you find a flavor that you like (that is how the book's chapters are divided ie. lemon, carmel, almond, vanilla etc), then you find an item in the chosen chapter that you want to make (cakes, cookies, muffins, pies, tarts), then you must have concentrated flavored ingredients to put into that recipe. For instance, a lemon pound cake is made with "lemon enhanced sugar". The sugar is simple to make but takes days to make. (Drying lemon peels - then letting them sit in granulated sugar until the sugar is lemon flavored). That is just one example of an ingredient that needs to be prepared in advanced. I used plain white unflavored sugar and it turned out fine. The purpose of the book is to make that lemon flavored poundcake EXTRA lemony. All flavors are supposed to be very enhanced and concentrated. Sounds good but I need to find the time to prepare all of these ingredients so that I can prepare the recipe at a later date. Many people would not have the time or patience for this book but I love to bake so I'm willing to try it out. It is kind of a pricey cookbook but it offers many, many recipes and an opening section that offers alot of helpful hints. It's beautifully laid out and has easy to read directions. If you have extra time to bake and you plan in advance, then I recommend this cookbook.
