The Trieste way with the great Adriatic spider crab (dialect 'granzievola'): the crab is purged, boiled, and its sweet white meat and coral picked from carapace and claws, then dressed with garlic, parsley, breadcrumb, lemon and oil, packed back into its own cleaned shell and gratinated until a crust sets. Served warm in the shell as an antipasto or a delicate second course, it is prized in spring when the crab is fullest; some households splash a spoonful of rum into the shell before filling.
The spider crab Maja squinado, named by the naturalist Herbst in 1788, is fished in the Gulf of Trieste and the shallow northern Adriatic; in Italian it is 'granceola' or 'grancevola', and Triestine dialect calls it 'granzievola', a name commonly explained as 'granzo' (crab) plus 'zeola' (onion), the spiny, rounded shell recalling an onion. Sold live and cooked like lobster, the crab is at its best in spring. The Trieste preparation — picked, dressed and baked in the shell — is quite distinct from the 'granseola alla veneziana', where the meat is simply dressed cold with oil and lemon and never baked.
Warm, sweet crabmeat, delicate and faintly briny, loosened with lemon and parsley under a thin golden gratin of breadcrumb; the coral adds a richer, almost buttery depth, and the shell keeps every spoonful moist.
Boiling sets the crab's proteins and makes the meat easy to free from the shell; letting it cool in its own water keeps it from drying and toughening. Lemon juice brightens and firms the picked meat, while breadcrumb absorbs excess moisture so the filling holds. In the oven the shell acts as a heatproof ramekin, and the dry top heat drives a Maillard browning of the crumb crust while the enclosed meat effectively steams in its own juices, staying tender.
Variations
A richer version starts from a soffritto of onion softened in butter with breadcrumb, parsley and the crab's coral, finished off the heat with lemon juice and zest and the picked meat. The Venetian 'granseola alla veneziana' serves the meat cold, dressed only with oil and lemon. Where live spider crab is scarce, cooks use ready-picked crabmeat packed into scallop shells or ramekins.

How it's made
7 steps · 40 min active + 50 min waiting
- 1180 min
Purge 4 live spider crabs in cold water for about 3 hours, changing the water several times to rid them of grit.
- 230 min
Bring a light vegetable broth (celery, carrot, onion, salt) to the boil; simmer the crabs 8-10 minutes, then leave them to cool gradually in the water so the meat stays tender.
Watch outLet the boiled crab cool in its own water rather than draining it hot — that's what keeps the picked meat tender instead of dry and stringy.
- 310 min
Detach and scrub the top shells; keep 4 clean carapaces to use as baking dishes.
- 425 min
Crack the bodies and claws and pick out all the white meat and the coral, discarding the gills; collect it in a bowl with any juices.
- 58 min
Dress the meat with 1 minced garlic clove, chopped parsley, half the breadcrumbs, lemon juice, olive oil, salt and pepper (a teaspoon of rum optional).
- 65 min
Pack the mixture back into the shells and dust the tops with the remaining breadcrumbs to form a crust.
- 730 min
Gratinate at 180°C for about 30 minutes, the last 5 under the grill, until golden; serve warm in the shell with lemon wedges.
Watch outGratinate just until the crumb top is golden — the shell shields the meat, but overbaking still dries the filling out.
