Chef Prudhomme's incredibly good food has brought people from all over America and the world to his restaurant, K-Paul's Louisiana Kitchen, in New Orleans. To set down his recipes for home cooks, however, he did not work in the restaurant. In a small test kitchen, equipped with a home-size stove and utensils normal for a home kitchen, he retested every recipe two and three times to get exactly the results he wanted. Logical though this is, it was an unprecedented way for a chef to write a cookbook. But Paul Prudhomme started cooking in his mother's kitchen when he was a youngster. To him, the difference between home and restaurant procedures is obvious and had to be taken into account.
