Authentic polenta (not the instant variety),an Italian cook's version of cornmeal, is ideal for making this dish. Ordinary supermarket cornmeal will do, but look for the "stome ground" variety, which is best for both flavor and texture. Also be sure to use top-quality Parmesan cheese, such as Parmigiano-Reggiano. This is a dish where it's important to plan ahead. Start the polenta at least 2 hours before serving because the prepared polenta needs to firm up in the refrigerator before being browned in a skillet.
