Fini revenues or results and techniques are very random !!! In the garbage! This cookbook has become my favorite book, I am not a professional nor the future winner of Masterchef, just a curious and perfectionist who loves to cook. The basic techniques are very well explained and illustrated, the equipment and its use as well. The technical and product information are very useful, I made my first galette AZ (puff pastry included) and it was a delight, as are religious, buttons etc ... Finally real techniques well explained, recipes, tips seriously and which operate in a real cookbook. Congratulations!
