Brodetto Marchigiano di Ancona — Adriatic Multi-Fish Soup with Vinegar
Brodetto all'anconetana is one of the 13 versions of the Marchigiani fish stew (brodetto is the diminutive of brodo — broth) — the Ancona version uses white wine vinegar as its acidifying agent (rather than tomato or lemon), producing a sharp, clean-flavoured broth that is quite different from the Port Recanati saffron version. The preparation requires at least 9 types of Adriatic fish: scorpion fish (scorfano), gurnard (capone/triglia), weever (tracina), cuttlefish (seppie), clams (vongole), mussels (cozze), mantis shrimp (canocchie), skate (razza), and other local fish. Each is added in order of cooking time. The vinegar acidifies the broth throughout cooking; the result is bracingly sharp.

The Method
1
In a heavy pot — terracotta is traditional — warm the olive oil over a moderate flame. Add the finely sliced onion and cook, stirring occasionally, until it is deeply golden and fully soft. The onion must not brown harshly; it should be sweet and yielding.
2
Add the crushed tomato — no more than three or four tablespoons. Stir it into the onion and allow it to cook briefly until the raw smell lifts and the oil takes on an orange tint. The tomato provides colour and body; it is not the base of a sauce.
3
Pour in the white wine vinegar in a generous splash. Allow it to cook into the base for a minute or two. This is where the dish lives or dies: the vinegar must be present in quantity sufficient to make the broth assertively and cleanly sharp throughout — a timid addition produces a generic fish soup, not brodetto all'anconetana.
From the canon — Brodetto all'Anconetana is the fish stew of Ancona — different from the Pesarese brodetto (which uses saffron and vinegar) and the Rossinese brodetto (minima… Brodetto all'Anconetana — Adriatic Fish Stew →
4
Add the cuttlefish pieces. Reduce the heat to very low — the broth must barely tremble, never boil. Cook the cuttlefish for 15 to 20 minutes, until the pieces have lost their translucency and are just tender when pressed.
5
Add the firm whole fish: scorpion fish, gurnard, weever, and skate. Arrange them in the pot without disturbing the cuttlefish beneath. Maintain the gentlest possible simmer and cook for approximately 10 minutes, until the flesh at the thickest part of the fish just begins to yield to the side of a spoon.
6
Add the medium fish — mullet or bream. Again, settle them into the broth without stirring. Cook for 7 minutes. The flesh should be just opaque through to the bone; the skin intact and unbroken.
7
Add the clams and mussels. Place the mantis shrimp on top of everything as the final layer. Cover the pot and cook for 3 to 4 minutes. The moment the bivalves open and the mantis shrimp have just turned opaque — though still slightly undercooked — remove from the heat. Residual heat in the broth will complete them in the bowl.
8
Season with sea salt now, and only now. Place thick slices of toasted bread in the base of each bowl or alongside the pot. Serve directly from the pot at the table, each diner serving themselves.
III
Quality Hierarchy
01
Reserve — All nine Adriatic species sourced live or same-day from the Ancona fish market; aged wine vinegar of demonstrable complexity; terracotta pot; Marchigiani pane casereccio baked that morning.
02
Estate — Seven or more Adriatic species, all day-boat; a good-quality white wine vinegar from a named producer; a heavy enamelled cast-iron pot as substitute for terracotta.
03
Market — A minimum of five species including at least one cephalopod, one shellfish, and two firm-fleshed fish; a sound commercial white wine vinegar; any heavy-bottomed pot that holds gentle, even heat.
04
House — Fewer than five species acceptable only if cuttlefish is among them and the vinegar quantity is uncompromised; the character of the dish depends on the acid, not on the number of species.

Sensory Tests
◇Smell. After the vinegar is added to the base, the broth smells sharply acidic and clean — not harsh, not merely wine-scented; this sharpness must persist into the finished broth.
◇Sight. The broth surface barely trembles throughout cooking — a rolling boil at any stage signals the heat must drop immediately.
◇Touch. The cuttlefish, when pressed after 15–20 minutes, yields without resistance but holds its shape; it is not rubbery.
◇Sight. Every bivalve shell has opened; the mantis shrimp have turned fully opaque on their exterior but carry no dryness — the moment these conditions coincide, the pot leaves the heat.
◇Sight. The broth is tinted a light terracotta from the tomato; it is clear, not cloudy — cloudiness indicates the heat was too high at some point.
◇Where it lives or dies. The vinegar must be added in sufficient quantity to make the broth bracingly and unmistakably sharp — the Ancona version is defined by this clean acidity, and any reduction of it produces an undifferentiated fish soup.
