The risotto base traditionally begins with a soffritto of finely diced onions gently sweated in butter, olive oil, or a combination of both. This slow cooking process caramelizes the onions' natural sugars, building a sweet foundation without browning. Regional variations might include celery, carrot, leeks, or shallots, each contributing subtle variations to the final flavor profile. The fat component – whether northern Italy's traditional butter or southern Italy's olive oil – influences both flavor and mouthfeel.

After the aromatics have softened, the raw rice is added and toasted in what's called the tostatura phase. This crucial step coats each grain with fat, creating a protective barrier that allows the rice to absorb liquid slowly while maintaining its structural integrity. The rice should become translucent around the edges while remaining white in the center – a visual indication that the grains are properly sealed but not overtoasted. This phase typically takes 1-2 minutes of constant stirring.

The final element of the base often includes deglazing with wine (typically dry white wine in most regions, though red appears in certain variations). This adds acidity and complexity while dissolving flavorful compounds that have developed on the pan's surface. The alcohol evaporates, leaving behind concentrated flavor that permeates the rice. Only after the wine has been completely absorbed does the gradual stock addition begin – marking the transition from base preparation to the main cooking process.

The broth or stock used in risotto constitutes the primary flavor medium, as each grain will absorb this liquid during cooking. Traditional risotto relies on light meat stocks (chicken, veal) or vegetable broths, each bringing distinct character to the dish. The quality of this component cannot be overstated – a well-made homemade stock brings depth impossible to achieve with commercial alternatives, though high-quality store-bought options can produce excellent results when enhanced with aromatics.

Temperature plays a crucial role in proper risotto technique. The stock must be kept hot (just below a simmer) throughout the cooking process. Cold stock added to the rice would shock the grains, halting the cooking process and resulting in uneven texture. Additionally, maintaining a proper temperature gradient ensures that the rice cooks through evenly while the exterior releases starch at a consistent rate.

The method of addition – ladle by ladle, waiting for each portion to be absorbed before adding the next – might seem unnecessarily laborious, but it serves a vital purpose. This gradual introduction of liquid, coupled with constant stirring, creates the perfect environment for the rice to release its starch while maintaining structural integrity. The rhythm becomes almost meditative: add, stir, absorb, repeat. While shortcuts exist (pressure cookers, baked methods), the traditional approach offers unparalleled control over the final texture.

Italian risotto rice varieties share key characteristics that make them uniquely suited to this cooking method. Their high amylopectin starch content (the sticky type of starch) creates risotto's distinctive creamy texture, while their structure allows them to absorb significant liquid while maintaining integrity. Unlike long-grain varieties that stay separate when cooked, these short, plump grains release their starch readily when properly agitated during cooking, creating the signature suspended starch that gives risotto its luxurious mouthfeel.

The three traditional rice varieties used for authentic risotto each bring slightly different qualities to the finished dish. Arborio, the most widely available internationally, has large, fat grains with reasonable starch content. Carnaroli, often called the "king of risotto rice," offers exceptional starch release while maintaining structural integrity throughout cooking – this balance makes it the preferred choice of many chefs. Vialone Nano, with smaller grains, absorbs flavors more quickly and creates extremely creamy texture, though with slightly less distinct grain definition in the finished dish.

Proper risotto cooking results in rice that maintains a specific textural contrast – the exterior should be soft and have released enough starch to create creaminess, while the center retains a slight resistance (not hard or chalky, but pleasantly firm). This "al dente" quality typically develops after 16-20 minutes of cooking, depending on the specific rice variety and freshness. The risotto should flow when plated, settling into a velvety pool rather than standing in a mound – what Italians poetically describe as "all'onda" or wave-like.

The final stage of risotto preparation – mantecatura (from mantecare, "to stir together") – is where true mastery reveals itself. After the rice has reached the perfect al dente texture, the pan is removed from heat, and cold butter, cheese, or other enriching elements are vigorously incorporated. This traditional technique serves several crucial purposes: it stops the cooking process immediately, preventing overcooked rice; it creates a stable emulsion as the cold fat meets the starchy liquid; and it introduces a final layer of flavor that harmonizes the entire dish.

The temperature contrast between the hot risotto and cold finishing ingredients is essential to proper mantecatura. When cold butter hits the hot rice, it doesn't simply melt – it emulsifies with the starchy cooking liquid, creating microscopic fat droplets suspended in the creamy base. This emulsion gives properly finished risotto its characteristic glossy appearance and velvety mouthfeel. Similarly, when cheese is added, the residual heat melts it gently without breaking its protein structure, maintaining a smooth integration rather than stringiness or graininess.

The final consistency of risotto is a subject of passionate debate among Italian cooks. Traditional Milanese risotto flows somewhat freely when plated – all'onda (wave-like) – while northern mountain versions might be slightly thicker. Regardless of regional preference, proper risotto should never be stiff enough to hold a shape, nor so loose it resembles soup. After mantecatura, the risotto should rest covered for 1-2 minutes before serving, allowing the flavors to harmonize and the texture to reach its ideal state. This brief rest also provides time to quickly prepare serving plates, ensuring the risotto is enjoyed at its optimum temperature.
