Prep Time: approximately 4 hours (cook time approx. 45 minutes.)
1. Bring water and chicken stock to a boil.
2. Add butter, dried mushrooms (crumbled), salt, sugar, and pepper.
3. Slowly add polenta, stirring constantly.
4. Reduce heat and keep stirring until mixture thickens (about 20 minutes). Use a long-handled wooden spoon, as mixture will bubble and pop.
5. Stir in grated cheese.
6. Add salt and pepper to taste.
7. Oil a large baking pan or dish, and spoon polenta in, smoothing it down.
8. Let it sit for at least 10 minutes.
9. Invert onto a platter or cookie sheet and cut into slices.
10. Serve hot, or put polenta slices on a grill to reheat.
