Beautiful Artwork, Delicious Treats
Format: Hardcover
I saw this book in a book store and was drawn to the beautiful artwork and simple recipes with gorgeous and more complex decoration. So far I have made one cake (the one with lime and white chocolate with almonds on top) and it was a HUGE hit with my husband. His comment was that he had to restrain himself from eating the whole thing!!

Page turner

The photos are stunning, the directions are excellent, the details are inspiring, the decorations are impressive. Even if I fail to make the recipes I enjoy reading the book over and over, living vicariously through the pages.

Not crafty/artistic .. maybe not for you.. if so.. some great ideas
Format: Hardcover
hmmm.. where to start.. firstly.. this is one talented artist/baker/author. The photos/end products in this book.. look incredible.. That being said.. I am a great baker.. not a great crafter/painter/drawer/artist. .. Many of the decorations involve drawing for making a stencil.. or sponge painting etc.. For the seashell recipe.. it starts with.. collect sea shells from the sea shore.. (not that practical) .. the hazelnut cookies have so few ingredients.. albeit.. an amazing decoration.. I doubted their deliciousness.. I loved the suggestion of using an open book to make your butterfly icing creatures.. to give them a in flight curved effect... I just dont see me ever doing that I did not make anything from this book.. i thumbed through it.. and returned it.. SO this is based purely on my own limitations of crafting/artistic ability.. hopefully a more ambitious home cook comes along and proves me wrong.
