If I happen to get a splotch of grease or a splash of sauce on the page of a cookbook, who cares? A stain like that gives character to the book, like blood on a turkey vest or a fishing hat that's faded after countless afternoons on the water. Then, the next time you flip to that stained page, you might think back on the moment it happened and smile. And there, without knowing it at the time, you've created a memory. Also, with cookbooks, you can share the recipes, either by lending the book to a friend or eventually passing it down to someone close to you. I have no plans of giving my iPhone away to anyone anytime soon.
