Cooking polenta: is stirring for 30 minutes really necessary?
It definitely does not need to be stirred continuously. Fairly frequently, yes, to avoid burning on the bottom, but not constantly. Cooking for more or less time has more impact on texture than flavor. Cooked briefly, you get more of a grain-like cream of wheat texture. Cooked long, you get a creamier, smoother result. Both can be good, but the creamy style is more traditional.
