Directions

1. Bring 7 1/2 cups water to a boil in a large pot over high heat.
2. Add 1 1/2 tbsp. salt and the bay leaves.
3. Whisking constantly, gradually add polenta. Reduce heat to medium and cook, whisking often, until mixture begins to thicken, then adjust heat to maintain a gentle bubble. Cook, stirring occasionally with a sturdy rubber spatula and scraping pot, until polenta is thick and creamy and grains are softened, 30 to 45 minutes. If it becomes too stiff to stir easily, add a little boiling water.

9. Pour one-third of polenta into dish, spreading evenly. Top with half of truffled cheese.
10. Add another one-third of polenta, then remaining truffled cheese. Dollop remaining polenta on top and spread evenly.
11. Sprinkle with parmesan and dot with remaining 1 tbsp. butter.
12. Bake torta until medium brown, bubbling on the edges, and hot to the touch, 40 to 45 minutes.
13. Let cool, then chill until cold, at least 2 hours and up to 1 day.
14. Cut torta into small rectangles (about 1 1/2 by 2 in.) and transfer to a baking sheet. Broil 4 inches from heat until browned and crisp, about 5 minutes.
