Query: Excellent and thorough study of Moroccan food from a true gourmet

Every review I'd read about Ms. Wolfert's book described it as a masterpiece of Moroccan food and culture and I've found that it certainly is. I bought the book after returning from Morocco along with another Moroccan cookbook. While Ms. Wolfert's book does not have the beautiful glossy color photos like the other book, she includes a wealth of information about the culture, history and people of Morocco as well as very detailed, delicious recipies. Each one I have tried has come out better than the vast majority of the food I actually ate in Morocco! A warning to those looking for fast, easy recipies, however. Ms. Wolfert is clearly a perfectionist and a purist and does not include many short cuts or substitutions, and Moroccan food is the original "slow food". If you crave authenticity, are willing to follow her recipies closely, and willing spend many hours preparing the dishes, you'll be handsomely rewarded.
