"Forgotten Skills of Cooking" by Darina Allen is a hardcover book published in 2009 by Kyle Cathie. Written in English, this book falls under the genre of general cookery and recipes, making it a valuable resource for anyone interested in cooking.
This is the most valuable 'cookbook' (I put that in quotes because it's far more than just a cookbook) I own. I'm a very experiences and diversified cook it teaches me things I never knew and reminds me of essentials I've forgotten.
