This recipe was entered in our We ♥ Local Cornmeal recipe contest by Anna Mays. Anna says,"Comforting, creamy Parmesan polenta is a dressed up in this recipe with sauteed wild mushrooms and porcini, simmered in a rich butter, soy and mushroom stock sauce. The umami flavor of the sauce brings out the sweetness of the corn. For polenta to lose its hard, gritty texture and turn creamy, enough water must penetrate the corn’s cell walls that the starch granules within swell and burst (or “gelatinize”). Similar to the preparation of dried beans, baking soda is added to the cooking liquid to reduce the time it takes for gelatinization to occur, thus shortening cooking time and making the polenta more creamy. Enjoy with a generous mound of mushrooms and sauce; a fun twist on a classic winter comfort food."
