Risotto's creaminess comes from starch, not cream: the constant stirring as hot broth is added ladle by ladle breaks down the surface of each rice grain and releases amylopectin, which thickens the liquid into the glossy, fluid consistency Milanese cooks call 'all'onda'—like a wave, not a solid mass. The technique begins with a soffritto and toasting the rice in fat before any liquid goes in; the wine deglazes the pan and adds acidity; the broth (kept simmering separately) goes in a ladle at a time. The final step, mantecatura, is off-heat: cold butter and Parmigiano beaten in vigorously until the risotto becomes emulsified and silky. Risotto alla Milanese—saffron, bone marrow, and white wine—is the archetype, but the technique is a blank canvas for mushrooms, seafood, vegetables, or cheese.
Heat the broth in a saucepan and keep it warm over low heat.
In a large, heavy-bottomed pot, heat the olive oil and 2 tablespoons of butter over medium heat.
Add the finely chopped onion and cook until it becomes soft and translucent.
Stir in the minced garlic and cook for another minute.
Add the Arborio rice to the pot and stir to coat the rice with the oil and butter. Cook for about 2 minutes until the rice is lightly toasted.
Pour in the white wine and stir continuously until the wine is fully absorbed by the rice.
Begin adding the warm broth one ladleful at a time, stirring frequently. Allow each addition of broth to be absorbed before adding the next. Continue this process until the rice is creamy and cooked to al dente, which should take about 18-20 minutes.
Once the rice is cooked to your liking, remove the pot from heat.
Stir in the remaining 2 tablespoons of butter and the grated Parmesan cheese. Mix until the butter and cheese are fully melted and the risotto is creamy.
Season with salt and pepper to taste.
Serve the risotto hot, garnished with chopped fresh parsley if desired.
Starch-released Italian rice dish; stirred continuously as broth is added. Finished with cold butter (mantecatura) off-heat.
Northern Italy (Lombardy, Piedmont, Veneto). Carnaroli and Arborio rice are grown in the Po Valley.
Carnaroli or Arborio rice, hot broth (chicken/vegetable/fish), white wine, butter, Parmigiano, soffritto.
