I've fiddled with a technique of adding old bread into new dough, which is known by its German name, Altus. The man who inspired my recent attempts has the great literary name "Pip," the hero of Charles Dickens' Great Expectations.
Pip is from Oz. Check out his amazing breads on The Fresh Loaf. Whether it's his impressive milling grains, use of biodynamic flours, or the array of different flawless breads on the site, he's terrific. Well, like another character from Dickens' novel (Mrs. Havisham) I almost put myself in flames, catching fire while tasting this "grain" loaf of his. Dickens' references aside…make this loaf, as you won't be dissapointed!
