I don't think I have any recipes memorized. For day to day cooking, I just look at what I have and combine guided by my taste and experience. Usually turns out good, sometimes great. It can be frustrating for guests, though. All I can do if they want the recipe is give some vague directions... More formal meals may be based on recipes--sometimes a combination of two or three. Baking is a different story. I don't bake that often--not mush of a sweet tooth--and I slavishly follow recipes. Baking, to my mind, is more science than art.
