Risotto is more a style than a recipe; I have a favorite risotto style that I made up myself. If you don't know what you're doing, though, I suggest starting with a basic mushroom & cheese risotto recipe (not included), instead of the no-cheese options below. Do not substitute anything American for the rice unless you know it works; use Italian arborio rice.
You also need a good pan: either enameled cast iron or a heavy-bottomed stainless steel pan works best. If you don't have one, you had better know what you're doing. My risotto pan is a somewhat wok-shaped enameled pan from Mario Batali that works well (but that I don't think they make anymore)--you can see it in some of the pasta pictures.
You don't have to use fresh stock; I have used cubes as well as some nice organic powdered stocks. Better Than Boullion is also good.
