A Neapolitan and coastal-Campanian way of cooking fish — often a whole white fish such as pezzogna, sea bream or sea bass — gently poached in «crazy water»: a light broth of water, tomato, garlic, chili, parsley and olive oil, sharpened with a little white wine. The fish simmers briefly in the thin, aromatic liquid until just cooked, and is served in its own broth, which is mopped up with bread or used to dress a little pasta. It is a fisherman's dish: fast, simple, and built on very few ingredients.
A dish of the Campanian coast, most commonly traced to the fishermen of the island of Ponza, in the Pontine islands off Naples and Lazio, though the islands of Capri and the fishermen of Capo Miseno also lay claim to it. The prevailing account places it in the late 19th century: at sea, fishermen are said to have poached their just-caught fish in seawater, sometimes with a little wine, rather than use salt — by one explanation (attributed to the historian Enrico Durazzo) because salt had become a heavily taxed and costly commodity. Tomatoes, garlic and herbs went into the same pot. The name «acqua pazza», «crazy water», is most often explained by this thin, improvised seawater broth. The restaurants of Naples and Capri later carried the dish and its catchy name to wide fame.
The fish comes out white, just-set and silky, falling cleanly from the bone, tasting cleanly of the sea rather than of sauce. The broth around it is thin and bright — not a thick sauce — tomato-sweet, salty, sharp with garlic and a whisper of chili heat, fresh with raw parsley and rounded by olive oil, with the wine cooked down to a faint tang. The point is balance and lightness; the bread you dip into the broth is half the pleasure. Overcook the fish and it turns dry and woolly; reduce the liquid too far and it stops being acqua pazza and becomes a heavy tomato stew.
This is poaching, not stewing or frying: the fish cooks in a liquid kept to a gentle simmer, never a hard boil, so the heat reaches the flesh slowly and evenly. Fish protein sets at a low temperature, and a violent boil would seize and toughen it and break a whole fish apart; the bare simmer keeps the flesh moist, silky and intact on the bone. The deliberately thin, watery broth — the «crazy water» — is what defines the dish against a tomato stew: there is just enough liquid to steam and bathe the fish and to build a light, brothy sauce, not to braise it down. The garlic, chili and tomato are softened in oil first to release their flavor into the water, while the parsley is added late or raw so its fresh aroma is not cooked out, and the wine is added early enough for its alcohol to cook off and leave only acidity.
Variations
The fish varies with the catch: a whole pezzogna (blue-spotted sea bream), orata (gilthead bream), branzino (sea bass) or San Pietro (John Dory) are classic, but fillets and even mixed seafood are used. Cherry tomatoes are common in summer, omitted by some for a paler «white» version; chili can be left out for a milder broth. Some cooks finish the broth over pasta — spaghetti or linguine all'acqua pazza — and shellfish such as clams or mussels are sometimes added. It should not be confused with a heavier tomato fish stew like cacciucco or a full guazzetto; acqua pazza is defined by its deliberately thin, light poaching liquid.

How it's made
7 steps · 15 min
- 110 min
Clean and scale the whole fish (or portion the fillets) and pat dry.
- 24 min
In a wide pan, gently warm olive oil with sliced garlic and chili until fragrant but not browned.
Watch outWarm the garlic and chili in the oil gently until just fragrant but still pale — let the garlic brown and it turns bitter and muddies the delicate broth.
- 35 min
Add halved cherry tomatoes and let them soften and start to break down.
- 45 min
Pour in the white wine and let it bubble until the alcohol cooks off, then add enough water to make a shallow, brothy pool.
- 52 min
Slide in the fish, season lightly, and bring to a bare, gentle simmer.
- 610 min
Spoon the broth over the fish and poach, never boiling hard, until the flesh is just set and pulls cleanly from the bone.
Watch outKeep it at a bare, barely-trembling simmer and spoon the broth over the fish until the flesh just sets and lifts cleanly from the bone — a hard boil seizes the flesh and breaks the fish apart.
- 72 min
Scatter with chopped parsley and a thread of raw olive oil, and serve the fish in its broth with bread.
