I'm a foodie in the whole sense of the word. I'm passionate about both eating and cooking as well as ingredients and technique. I'm going to go shopping for cookbooks soon and want to buy books to grow my small collection. I'm not looking for generic, common recipes but for the bibles of the culinary world. I'm more interested in the techniques and ingredients of exotic cuisines. I already own the red plaid bhg cookbook which was good for me but not so much lately since I've grown so advanced in my cooking and want more authenticity and more of a challenge. I'm looking to buy Julia child's mastering the art of French cooking and Diana Kennedy's The Essential Cuisines of Mexico. Any other recommendations of all time must haves?
