Using a heavy, large pot (I like my large cast iron pan but an enameled stock pot works too), heat 3 Tablespoons olive oil over medium heat for about 30 seconds. Add ½ cup minced onion and 2 Tablespoons shallot. Cook them until golden, stirring often, about 5 minutes.
Add 2 ½ cups rice and stir to coat with the oil in the pan. Cook the rice until the edges become translucent, only a minute or so. Add ½ cup wine and the sliced orange rind and stir well until the wine is absorbed. This only takes about 30 seconds. Add 1 teaspoon salt and stir again.
Start the process of adding your chicken broth now (see notes below regarding keeping the broth hot). Add between ½ to ¾ cup at a time, stir until each portion is almost fully absorbed, then continue adding small amounts of the broth, waiting for the rice to absorb it each time before adding more, stirring all the while, almost continuously (all this stirring is making the risotto starchy for that creamy texture you're after). If the broth bubbles too much, turn the heat down a little, you don't want the liquid to steam off before the rice can absorb it. This step can take up to 20 minutes.
When all the broth has been added and the risotto now has kind of a creamy, starchy thickness to it, add in ¾ cup orange juice and stir again to distribute and absorb. The rice should be creamy and tastes al dente. (See recipe notes if rice's texture is still too firm.)
Remove from the heat. Add ¾ cup cheese and stir until melted and distributed well. Add 4 Tablespoons butter and also stir until melted. Taste the risotto now, adding more salt if needed, and black pepper, if desired. If you like more cheese in your risotto, you can more at this time, stirring to incorporate.
Serve immediately, ladling into shallow bowls. Garnish the Risotto with a slice of orange, optionally, for presentation and sprinkle with extra cheese and black pepper.
