Deglaze - Deglazing the pan at this point isn't strictly necessary, but a splash of white wine will add another layer of flavor and help lift up any bits that have caramelized to the pan. Use a 1/2 cup or so of wine, and simmer until the wine has completely reduced and the pan is nearly dry.
Cottura - Begin incrementally adding the warm broth one ladle at a time. Wait to add another ladle until the liquid has been almost completely absorbed by the rice. This gradual addition of liquid is key to getting the rice to release its starch and create its own delicious sauce, so don't rush this step. Ideally, you want to use just enough broth to cook the rice and no more.
