I did some googling of a couple of things Bertie and Aunt Dahlia come up with for his post-chokey dinner (in Code of the Woosters) and some nice person has a site where a notable chef has taken a stab at making some of those things. I don't think the ingredients are doable, because some of them entail pickled pork tongue or truffles and whatnot.

Also I've deciphered a few of the meals given in Code of the Wooster. For example Consomme aux Pommes d'Amour is tomato soup and Salade d'endive et de celeri is (I'm guessing) endive and celery salad.
