Make this dish when wild mushrooms become available at your local farmers’ market. The greater the variety of mushrooms, the more flavor your risotto will have — each mushroom adds its own complex flavor, aroma and colour.
In a large skillet, melt 2 tbsp of the butter over medium-high heat. Add mushrooms, cauliflower, a pinch of salt and a splash of water; sauté until liquid is evaporated and mushrooms appear dry, about 15 minutes. Transfer mushroom mixture to a plate and set aside.
In the same skillet, melt 2 tbsp of the butter over medium heat. Add shallots and pancetta; sauté until shallots are softened, about 2 minutes. Stir in rice until well coated (do not let brown). Stir in wine and cook, stirring constantly, until liquid is absorbed. Stir in 1/2 cup stock and cook, stirring constantly, until stock is absorbed. Continue adding stock, 1 cup at a time, stirring constantly until absorbed before adding more. It will take about 20 minutes to incorporate all the liquid.
Stir in mushroom mixture and cook until vegetables are tender and rice is creamy, about 5 minutes. Stir in the remaining butter, cheese, parsley and thyme. Season to taste with salt and pepper. Let stand for 2 minutes.
Ladle risotto into warm bowls and garnish with shaved truffle or drizzle with truffle oil.
