The basic method of making risotto will never change; you cook the rice slowly and add broth gradually, so the starchy inside of the rice kernel expands as the outside layer dissolves into creaminess. Risotto feeds the soul and can take a whole range of flavors. I like the pumpkin risotto here, but try a shrimp risotto using shellfish broth, adding a pound of peeled shrimp at the last minute and letting them cook no more than 5 minutes. Or how about a green risotto, with a bunch of watercress or a few handfuls of spinach, chopped fine? Or a mushroom risotto with a pound of sliced fresh mushrooms added to the dried porcini mushrooms.
Keep in mind that there's a lot of bad risotto out there, usually because folks overcook it or add too much wine. But if you do have some white wine open, add a splash or two to the rice and onions, just before you ladle in the broth. It gives yet another dimension of flavor.
