Anna and Kristina test recipes from one of the most influential books - not just cookbooks - of all time, "The Joy of Cooking". They are using the 75th anniversary edition of the book. From the book which has gone through transformations over its history but which still retains many old fashioned recipes, they are making both new and old dishes, six in total, in four and a half hours: caldo verde, grilled salmon with watercress mayo, cheese soufflé cockaigne, ham steak with red-eye gravy, green beans with onions, tomatoes and dill, and plum pudding with hot foamy sauce. Their international guest chef taster is Tom Douglas, a Seattle based restaurateur who owns no less than five restaurants. He considers "The Joy of Cooking" one of his favorite cookbooks. Regardless of Chef Tom's evaluation, Anna and Kristina are hoping to feel the joy when they're cooking. Meanwhile, they test various potato peelers and taste test various types of salts as finishing salt.
