I have several of the BOTB cookbooks, including New Mexico. I like it and have made several recipes from it. It's a compilation of recipes from several different cookbooks. Most tend to be from local cookbooks. Things like fire station cookbooks, various fund raiser cookbooks, as well as more famous books. Be aware that all of these books also have every day recipes that you might find in nearly any cookbook, such as Betty Crocker. For example, there is a recipe for streusel filled coffee cake. But, I think it's still a good book to represent New Mexican cooking.
Another one, if you can find it, is called Savoring the Southwest. A cookbook and more from the land of enchantment (New Mexico). I don't know if the original book is still in print, but I believe there might be a version 2. Again, it has many New Mexican recipes, and more general recipes. This book is pretty neat in that it has lots of pictures from artists of the southwest, such as Henriette Wyeth. Another neat thing about this book is it has old clippings from various New Mexico newspapers. For example - From the Roswell Register, April 3, 1896; "Choice imported and domestic wines are to be obtained at the Legal Tender." This book is a fund raiser for the Roswell Symphony Guild.
Both are good examples of New Mexico cookbooks.
