It's impossible to say which book is the worst without having forensically read all of them in granular detail. This is the book that contains such delights as rinsed beef and mandarin 'feijoada', the provocative shroud of cannellini beurre blanc, the infamous rinsed hoop pasta e ceci and a meatloaf comprising cooked meat, pears and (of course) stuffing mix. There is on the other hand the book which has spaghetti with dried mushrooms and white chocolate to consider. Swings and roundabouts innit.
