Valle d'Aosta, northwestern Italy
The canonical polenta preparation of Valle d'Aosta, known locally as polenta grassa (fat polenta) or polenta concia. Stoneground yellow polenta — coarser than standard commercial maize flour — is cooked in salted water over a fire or induction plate, stirred continuously with a wooden paddle for 50–60 minutes until it comes away from the sides of the copper pot in a single mass. In the final ten minutes, generous quantities of diced Fontina DOP and cold unsalted mountain butter are added in stages, stirred in vigorously until fully incorporated and the polenta is shiny, very rich and pulls in long strings. Served immediately from the pot onto wooden boards or pre-warmed plates. Nothing else needed.
Starchy, deeply savoury maize; milky, slightly pungent Fontina in long molten strands; mountain butter adds a clean fat richness; salt is the only seasoning and must be generous.
{"Use coarse stoneground polenta, not instant or fine-ground: the coarser texture provides the correct bite and takes the full 50 minutes to hydrate properly","Stir continuously and vigorously: the constant agitation breaks up lumps and develops the starch structure necessary for proper set","Add butter and Fontina in the final 10 minutes only — too early and they separate; too late and they don't incorporate fully","The butter must be very cold when added to create an emulsion rather than pooling on top","Serve immediately from the pot: polenta concia stiffens quickly and cannot be successfully reheated to the same texture"}
{"A copper paiolo (traditional polenta pot) conducts heat more evenly than steel or cast iron, reducing the risk of scorching the bottom","Substitute a third of the water with whole milk for extra richness — a refined restaurant variation","Allow the final polenta to rest in the pot for 5 minutes off heat with the lid on before adding butter and Fontina — the residual heat and steam help create a more cohesive mass"}
{"Using instant polenta: the texture and flavour are fundamentally different and insufficient cooking time means the starch doesn't fully gelatinise","Adding the Fontina too early — it breaks down, the fat separates and the polenta becomes greasy rather than creamy","Under-salting the cooking water — properly seasoned water is the only chance to salt polenta as it cannot be adequately adjusted after the Fontina is added","Using warm butter instead of cold — warm butter doesn't emulsify and produces a greasy rather than silky result"}
