I couldn't find any prepared polenta so I made my own with corn meal. I boiled 3:1 ratio of salted water to cornmeal for 25-30 mins stirring often with a whisk. It became very thick and dense. I placed it in a buttered dish and let it cool for 15 minutes as it takes the shape of the dish. Then it was ready to cut up and use in the recipe. I followed the rest of the recipe as is and it turned out beautifully. My partner said it was one of my best meals! We loved it! I would make this for company for sure.
