03Heat the broth to boiling. Turn the heat to very low under the broth to keep it warm. Begin adding the broth to the rice mixture about half a cup at a time, stirring constantly to prevent sticking. As the rice absorbs the broth add more warm broth. Continue adding broth until the rice is al dente, tender outside but with a little bite at its center, and the mixture is quite moist, about 25 minutes total cooking.04Turn off the heat and stir in the remaining butter and the six tablespoons of grated pecorino Romano cheese. Serve extra grated cheese at the table.
