Reinterpreted Vicenza Style Stockfish with White Polenta | Baccalà alla Vicentina Rivisitato con Polenta Bianca
This is the version of baccalà alla vicentina that takes the dish apart. The traditional Sandrigo recipe layers everything in one pot and leaves it alone for five hours until fish and sauce become a single creamy body. Here the two are cooked separately and reunited only at the pass, so the stockfish arrives in intact ivory flakes with a sauce spooned over it rather than dissolved into it.
Under it goes polenta bianca, made from Biancoperla, the pearl white maize of the Veneto plain. Not a stylistic choice: white polenta is what the lowland Veneto and Venice have always eaten with fish, and yellow is the polenta of the mountains behind Vicenza. The flavour is softer and milkier, and it lets the onion and anchovy sauce sit forward instead of competing with a strong maize sweetness.
Everything that made the original work is still here: the same onions melted to nothing, the same salted anchovies, the same whole milk and olive oil, the same grated cheese. What changes is the order of operations and the temperature the fish sees, and that is enough to move the dish from a braise to a plated secondo without losing what it is.
Yield: 6 servings. Soaking: 48 to 72 hours. Prep: 50 minutes. Cook: 1 hour 20 minutes. Total active time: about 2 hours 10 minutes. Difficulty: advanced. Course: secondo. Region: Veneto, the province of Vicenza and the plain toward Venice.
The Story
Biancoperla is the reason this plate looks the way it does. It is a white maize of the eastern Veneto plain, with long pearly kernels and almost no carotene, and until the middle of the twentieth century it was the ordinary polenta of Venice, Treviso and the Vicenza lowlands. Hybrid yellow varieties replaced it after the war because they yielded more, and by the 1990s it had nearly vanished. A Slow Food Presidium took it on in 2002 and a handful of growers kept the seed alive. Stone ground, it cooks paler and milder than yellow maize, and it has always been considered the correct partner for fish in this corner of Italy.
The fish is not salt cod at all. Despite the name the Veneto gives it, baccalà alla vicentina is made with stoccafisso, cod split and air dried on wooden racks in the Lofoten islands through the Arctic spring, without a grain of salt. Vicenza buys a specific grade, ragno, the thickest and palest fish of the season, and that grade matters more than anything a cook does afterwards. Dried this way the cod loses about eighty percent of its weight and concentrates its gelatin, which is what later lets the sauce thicken with no flour and no cream in it.
Reinterpreting this dish in the Veneto is not a neutral act. The Venerabile Confraternita del Bacalà alla Vicentina, founded at Sandrigo in 1987, fixed a written reference version, and every September the town serves thousands of portions of it at its Festa del Bacalà, always with soft white polenta beside it rather than under it. Since then the province has argued about what may be changed, and a recipe that separates the fish from its sauce would not be accepted there as the real thing. It is not offered as such. It is what a number of Veneto kitchens started doing in the 2000s once they wanted the stockfish to read as fish on the plate: keep every ingredient, change only the heat and the sequence.

Preparation
Soaking the stockfish
Beat the dried fish firmly with a mallet or the back of a heavy pan to open the fibres, then submerge it in plenty of cold water in the refrigerator for 48 to 72 hours, changing the water every 8 hours. Thick ragno pieces need the full 72. It is ready when uniformly pliable and a skewer meets no hard resistance at the thickest part. Undersoaked stockfish stays leathery at the centre and no cooking will correct it.
Skinning, boning and portioning
Drain the fish and pat it dry. Remove the skin in whole pieces and set it aside for the garnish rather than discarding it, then run your fingers along the flesh and pull out the bones, which slide free easily once soaked. Cut the flesh into portions of about 5 oz (140 g), as even in thickness as you can manage. Keep them cold until the sauce is built.
Melting the white onions
Warm the olive oil in a wide heavy pan over the lowest heat, add the sliced white onions and a pinch of salt, cover, and cook 40 minutes, stirring every 10 minutes. They must go completely soft and translucent without taking colour. This is the longest step and the one most often rushed. Browned onions bring a caramel sweetness that has no place here and turns the finished sauce muddy rather than ivory.
Building and blending the sauce
Add the boned anchovies to the melted onions and stir until they dissolve, about 2 minutes. Pour in the white wine, raise the heat and let it evaporate. Transfer everything to a blender with half the milk, blend until completely smooth, then pass it through a fine mesh sieve back into the pan. Stir in the parsley and the Grana Padano off the heat. You want a pale, loose, glossy sauce with no visible onion in it.
Holding the fish at 145°F (63°C)
Lay the portions in a single layer in a wide pan, pour over the remaining milk and the olive oil, and season lightly. Bring the liquid to 145°F (63°C) on a probe thermometer and hold it there 25 to 30 minutes, never letting it simmer. At this temperature the flesh sets into firm white flakes and releases its gelatin slowly. Take the pan off the heat and let the fish rest in the warm liquid while you finish the polenta.
Cooking the Biancoperla polenta
Bring the water and milk to a boil with the salt, then rain in the Biancoperla flour in a thin stream, whisking hard to prevent lumps. Drop the heat to the lowest setting and cook 45 minutes, stirring with a wooden spoon every few minutes and scraping the base and corners. Stone ground white maize needs the full time to lose its raw floury taste. Beat in the butter at the end and keep it covered over hot water.
Thickening the sauce with the fish liquid
Lift the fish onto a warm tray. Strain the cooking liquid, which now carries all the gelatin the stockfish gave up, and whisk 1/2 cup (120 ml) of it into the onion sauce over low heat until the sauce thickens slightly and turns glossy. Taste and adjust the salt now, remembering the anchovies and cheese have already seasoned it. Do not return the fish to the pan: the sauce goes over the fish at the plate.
Crisping the reserved skin
Scrape the reserved skin clean, lay it flat between two sheets of parchment, weight it with a second tray and bake at 350°F (175°C) for 12 to 15 minutes, until rigid and lightly golden. Break it into shards as it cools. This gives the plate its one crisp element and uses a part of the fish that is normally thrown away after a soak that took three days.
Plating
Use genuinely warm plates, because white polenta stiffens fast and the sauce is an emulsion that dulls the moment it cools. Spoon a pool of polenta slightly off centre and spread it with the back of a warm spoon into a shallow oval rather than a mound.
Set a portion of stockfish on the polenta without breaking it up, spoon the onion sauce over the fish so it runs down to the edges, and stand two shards of crisped skin against it. Finish with a few drops of olive oil, a turn of white pepper and three small parsley leaves. Nothing else belongs here, and in particular no lemon, which flattens the milk and the cheese on contact.
Professional Technique
The controlling technique is holding the fish at 145°F (63°C) instead of braising it. Cod proteins begin setting around 122°F (50°C) and the muscle fibres contract hard above about 158°F (70°C), squeezing out moisture and leaving the flesh dry and stringy. Traditional baccalà alla vicentina works despite this because five hours in milk and oil eventually break the fibres into a creamy mass, so the drying does not matter. For intact flakes you have to stay below the contraction point and hold there long enough for the collagen to convert. A probe thermometer is not optional.
The second technique is thickening the sauce with fish gelatin rather than flour. A three day soak returns a great deal of water to the stockfish but the concentrated collagen stays, and it leaches into the milk during the low temperature hold. Whisking that strained liquid into the blended onion base gives a sauce that coats a spoon and holds its gloss without a gram of starch. Add it warm and off a hard boil.
Texture and Moisture Control
Three textures have to land at once and each fails differently. The fish dries above 158°F (70°C) and turns to cotton, which is irreversible. The sauce splits if the pan boils after the Grana Padano is in, because cheese proteins tighten and force the oil out. The polenta thickens continuously as it stands, faster than yellow because the grind is finer. Hold it covered over hot water and loosen it with hot milk as it stands.
Moisture also moves on the plate. Polenta releases water as it sits, so spread it thin and serve immediately rather than holding it in the bowl while the fish is portioned. The crisped skin goes on last and leans against the fish, never under the sauce, since it loses rigidity within thirty seconds of contact with anything wet.
Professional Mise en Place
This is a three day commitment at the soaking stage and a forty minute one at service. Almost all the work can be staged, but the polenta and the plating have to happen together.

Chef Tips
Buy stockfish already beaten if your fishmonger offers it, and ask for ragno grade specifically. The cheaper grades are thinner, greyer fish from late in the season, and they soak unevenly, the thin parts turning to mush before the thick parts soften. No technique rescues poor stockfish.
If you cannot find Biancoperla, use any stone ground white polenta rather than switching to yellow. Yellow maize is sweeter and more assertive, and it pushes the delicate onion and anchovy sauce into the background.
Taste the sauce only after the fish gelatin has gone in. The anchovies, the Grana Padano and the reduced liquid each bring salt, and the sauce tastes markedly different once thickened. Salting it while it is still loose is the commonest way this dish ends up overseasoned.
Save the strained cooking liquid you do not use. It sets to a firm savoury jelly in the refrigerator and is excellent melted into a risotto or a bean soup within two days.
Common Mistakes
Cutting the soak short. Stockfish given 24 hours instead of 48 to 72 stays leathery in the middle and never recovers. Change the water every 8 hours and test the thickest part with a skewer before you commit.
Letting the onions take colour. Caramelised onion brings a sweetness that has no place in this sauce and turns the finished colour from ivory to muddy brown. Lowest heat, lid on, 40 minutes, stirring often.
Boiling the fish. Above about 158°F (70°C) the muscle fibres contract and force out moisture, and the flakes go dry and stringy. Hold the milk at 145°F (63°C) with a probe for the full half hour.
Boiling the sauce after the cheese goes in. Grana Padano proteins tighten at a boil and break the emulsion, leaving oil on a grainy base. Add the cheese off the heat and keep the sauce below a simmer from then on.
Adding lemon or tomato. Both are tempting on a milk and fish dish and both are wrong. Acid curdles the emulsion on contact and tomato buries the anchovy. If the sauce tastes flat it needs salt, or more of the fish liquid.
Wine Pairing
Erbaluce di Caluso DOCG: A high acid white from the moraine hills of northern Piedmont, and the cleanest counterweight on this list to a sauce built on milk, oil and cheese. Its green apple and wet stone character cuts the fat without adding sweetness, and the slightly bitter finish picks up the salinity of the anchovy rather than smothering it.
Offida Pecorino DOCG: From the Marche, and the bottle to choose if you want weight as well as acidity. Pecorino has real body and a herbal, almost sage like edge that runs alongside the melted onion, and enough structure to stand up to the gelatin thickened sauce. Serve it at 50°F (10°C) so the texture shows.
Roero Arneis DOCG: Arneis is softer and rounder than the two above, with white pear and a distinct almond note on the finish. That roundness mirrors the white polenta directly instead of contrasting with it, which makes this the gentlest pairing here and the right one if your sauce has come out particularly rich.
Alto Adige DOC Pinot Nero: A red with this dish works only if it is pale, low in tannin and served cool, and the mountain Pinot Nero of the Alto Adige is exactly that. At around 57°F (14°C) its red fruit and undergrowth notes meet the crisped skin and the anchovy without any tannic clash against the fish.
Oltrepò Pavese Metodo Classico DOCG: Traditional method sparkling from Lombardy, mostly Pinot Nero vinified white. The fine bead scrubs the palate clean between mouthfuls of a genuinely fatty sauce, and its bready autolytic character sits well beside the maize. Choose a brut rather than an extra brut, since the dish carries no sugar of its own.
Storage & Reheating
Store the three elements apart. The cooked stockfish keeps covered in a little of its strained liquid in the refrigerator for 2 days. The onion sauce keeps 3 days sealed and tastes rounder on the second day. Cooked polenta keeps 3 days and sets firm, which is useful rather than a problem: a chilled slab cut into fingers and pan fried in butter is a good thing in its own right.
To reheat the fish, warm it in its own liquid in a covered pan over the lowest heat until it reaches about 130°F (55°C), never in a microwave, which drives it straight past the point where the flakes tighten. Reheat the sauce gently and whisk it back together if it separated in the cold. Loosen the polenta with hot milk over low heat, beating hard until pourable. The fish and the sauce both freeze acceptably for 1 month in sealed containers. The polenta does not: it turns grainy on thawing. Crisped skin cannot be stored and must be baked fresh.
