Ok, so maybe we can't vouch for anything written in this book, but it's worth noting. Certainly. Unmentionable Cuisine by Calvin W. Schwabe from 1979. Your prefect reference if you want to know how to fry Tripe (Tripes Frites), or prepare Grilled Calf's Liver (Foie de Veau Rôti), or perhaps this evenings Lung Stew (Lungenragout). Bon Appétit!
