Reconstruction
On 23 September 2026, as Tarragona marks the central day of Santa Tecla, espineta amb caragolins occupies a place at the table as distinctive as the city’s processions and human towers are in the street. It is a rich casserole of salted tuna pieces, small land snails and vegetables cooked in olive oil. Espineta is not an anatomically uniform cut: historical Catalan usage can denote salted fin-adjacent flesh, thin tuna meat or bony pieces with flesh still attached. In Tarragona it has commonly represented a strongly flavored, relatively inexpensive product of tuna processing.
No document establishes when the complete dish first appeared. Local accounts associate it with fishing families, particularly those of the Serrallo quarter, who made use of tuna portions that commanded less money than loins or belly. That origin is plausible but remains received history rather than a securely dated event. Firmer evidence comes from twentieth-century recipes and festival records. Tarragona’s 1986 Santa Tecla program described the stew as former festive food of the city’s modest classes and interpreted its tuna and snails as a meeting of fishing and farming communities.
The municipal recipe attributed to Dionisia Somolinos Aragón records a version learned from her grandfather, who cooked at Fonda Ca l’Ambròs in the 1940s. The salted espineta is soaked and repeatedly given fresh water. The snails are heated slowly until they emerge, then boiled with thyme and chili. Onion and garlic form the sofregit, seasoned with paprika; green and red peppers and aubergine are fried into a samfaina-like vegetable mixture. The tuna is sautéed with white wine before the vegetables and crushed tomato are incorporated. The boiled snails go in near the end, and the finished casserole is left to rest so its concentrated flavors combine.
The association with Santa Tecla is now stronger than any claim about the stew’s precise invention. The relic of the saint’s arm reached Tarragona in 1321, and the basic civic and religious sequence of the festival was recorded in 1369–1370. The dish itself is not documented that early. Its place in popular memory is expressed by the Ball de Dames i Vells verse asking what Tarragona will eat for lunch and answering: espineta amb caragolins.
Today the stew appears at communal tastings, fork breakfasts, restaurants and family meals during the festival. Recipes vary in vegetable proportions, seasoning and the tuna cut employed. What survives is not one immutable formula but a civic practice: desalting a preserved maritime ingredient, combining it with snails and garden produce, and turning once-humble foods into an annual statement of Tarragona identity.

Historical context
At this time, September 2026, Tarragona is holding a multi-day Santa Tecla program extending through September 24, with September 23 as the patronal feast’s central day. The celebration stands 705 years after the documented arrival of the arm relic in 1321. Its processional framework is itself medieval—annual rites are recorded in 1369 and formal ordinances in 1370—but many present-day elements, organizations and gastronomic events reflect later revival and expansion, especially since the 1980s.
Evidence
Written sources
ModerateMunicipal festival programs and modern cultural records directly establish the dish’s association with Santa Tecla by the late twentieth century, but do not establish its first appearance.
Recipe evidence
StrongTarragona’s municipal recipe identifies its informant, her line of transmission and the association with Fonda Ca l’Ambròs in the 1940s, while providing ingredients and a detailed method.
Food identification
ModerateEspineta is securely a salted tuna product, but scholarly terminology shows that the anatomical part denoted by the name varies by locality and period.
Dating
LimitedThe 1940s fonda preparation and later municipal records are documented; claims that the complete dish is substantially older are plausible but presently undated.
Preparation method
StrongSoaking the salted tuna, boiling the snails, preparing the vegetable sofregit or samfaina, combining the components and resting the stew are directly described in the municipal recipe.
Geographic attribution
StrongMunicipal, regional heritage and media sources consistently identify the dish with Tarragona and its Santa Tecla celebration.
Historical interpretation
InterpretiveThe characterization of tuna and snails as a symbolic union of Tarragona’s fishing and farming classes is explicitly present in a 1986 municipal text, but it is an interpretation rather than proof of the dish’s origin.

Limitations
- moderatedescription.food identification
The description defines espineta solely as salted tuna backbone. Scholarly tuna terminology shows that espineta varies by locality and may denote fin-adjacent musculature, thin salted flesh, or bone, fins and tail with adhering meat; Tarragona’s municipal recipe also distinguishes a loin-associated form. Describing it as a variable salted tuna cut or processing by-product is more accurate.
