Mantua's defining cold fish course: pike poached in an aromatic court-bouillon, painstakingly boned while still hot, then steeped overnight under a cold sauce of dissolved anchovies, capers, parsley, and garlic — served the following day at room temperature alongside grilled or fresh polenta.
Pike from the Mincio lakes were the Gonzaga dukes' preferred freshwater fish, raised specifically for the ducal table; Bartolomeo Stefani's 1662 L'arte di ben cucinare, written while serving as head cook at the Gonzaga court in Mantua, records freshwater fish from the Mincio as central to the court's banquets. The dish belongs to Mantua's deep tradition of piatto di magro — lean fast-day cooking shaped by the abundance of freshwater fish in the Mincio basin. Two village preparations on the Mincio, the luccio in salsa of Pozzolo sul Mincio and of Rivalta sul Mincio, have each received Denominazione Comunale (De.Co.) recognition.
Cold and savoury-sharp: the pike flesh is tender yet firm, its delicate freshwater sweetness half-buried under an oily, briny slick of anchovy and caper that has mellowed overnight; a slab of charred polenta brings smoky sweetness to cut the salt.
Poaching in an acidulated court-bouillon (vinegar, aromatics) at 80-90 °C coagulates pike protein gently, keeping the flesh tender while acid slightly firms the outer muscle fibres for cleaner deboning. The anchovy sauce is a loose emulsion: anchovies dissolve in warm olive oil, releasing protein fragments and fatty-acid droplets that suspend in the oil, simultaneously releasing glutamate and inosinate for deep umami. Overnight cold marination (below 4 °C) drives osmotic penetration of salt and acetic acid from the capers and vinegar into the pike flesh, firming and flavouring it gradually from outside in.
Variations
Some recipes add golden raisins or sweet vinegar-pickled peppers (agrodolce), echoing the Gonzaga court taste for sweet-sour contrasts. In cooler months the dish is occasionally served warm rather than cold. In the Alto Mantovano, freshwater perch substitutes for pike when scarce.

How it's made
7 steps · 30 min
- 110 min
Prepare a court-bouillon: bring a large pot of water to a simmer with celery, carrot, onion, bay leaf, and a generous splash of white wine vinegar; simmer 10 minutes to extract flavours.
- 222 min
Add the cleaned whole pike (head, tail, and innards removed); maintain a gentle poach at 80-85 °C — about 18-22 minutes per kilogram — until the flesh just begins to flake from the bone.
Watch outHold the poach at a bare 80-85, never a boil — the flesh should just begin to flake, past that the pike breaks apart when you debone it.
- 315 min
Lift out the pike; while still hot, use a small knife to peel away the skin, then separate both fillets from the spine and methodically extract all pin bones; arrange deboned pieces on a wide serving dish.
- 48 min
Make the sauce: warm olive oil in a small pan over low heat; add roughly chopped anchovies and stir until dissolved into the oil; remove from heat and stir in rinsed capers, finely chopped parsley, and minced garlic.
Watch outStir the anchovies into warm oil until they melt away completely — if the oil's too hot they fry and turn bitter instead of dissolving.
- 55 min
Pour the warm sauce evenly over the pike pieces; add salt-packed capers (rinsed and soaked 30 minutes) and, if using, diced sweet-vinegar peppers for an agrodolce note.
- 6480 min
Cover tightly with film; refrigerate for at least 2 hours, preferably overnight, so the sauce penetrates the flesh.
Watch outGive it at least a couple hours cold, ideally overnight — this is the step where the sauce actually penetrates the flesh.
- 730 min
Remove from refrigerator 30 minutes before serving; drizzle with raw extra virgin olive oil and a grind of black pepper; serve alongside slices of fresh or grilled polenta.
