Give two cooks the same ingredients and the same recipe; it is fascinating to observe how, like handwriting, their results differ. After you cook a dish repeatedly, you begin to understand it. Then you can reinvent it a bit and make it yours. A written recipe can be useful, but sometimes the notes scribbled in the margin are the key to a superlative rendition. Each new version may inspire improvisation based on fresh understanding. It doesn't have to be as dramatic as all that, but such exciting minor epiphanies keep cooking lively.
