This is a doctoral thesis and complete cookbook all in one. This was given to me as a gift and it is not only informative, but the recipes REALLY WORK. I have a lot of cookbooks, but I will never give this one up, ever. IT has hundreds of recipes with very simple ingredients. Even substitutions for ethnic seasonings is already provided in the book. It is healthy, tasteful, easy to cook and you dont need to be a genius to have wonderful meals with this one. EXCELLENT BOOK.
