Cynthia Graubart attained culinary celebrity status last year when she won a James Beard Award for the cookbook she co-wrote with famed Southern author Nathalie Dupree. It’s called Mastering the Art of Southern Cooking, and it is amazing. It took four years to write, and it weighs six and a half pounds. It’s got 750 recipes and another 650 variations on the standards. It is becoming itself a standard--a bible--for any Southern cook.
