I loved it !!!! Lots of good ecological and economic ideas! I have not yet tested any that interest me, but that I tested was fine. What interests me most are the preparations which can be prepared in advance and store-and there are full-. Of course, if you want to do it 100%, need time because many recipes are to prepare just before use, and that you still want to do it! But why not for some ... To each to his sort! The explanations are accurate. The amounts used are indicated, well organized by theme book, really great!
