Origins and history

Mojama is among the oldest cured foods still made in Spain, with roots in the Phoenician trading post of Gadir, now Cadiz, where tuna was packed in sea salt so it could keep and travel. Its name comes from Arabic words meaning dry or waxed, a trace of the long Moorish presence along this coast. The craft is strongest today in Barbate in Cadiz and in Isla Cristina in Huelva, both of which hold protected geographical status. Tuna for the best grades is still taken by traditional net fishing and only the loins are used. Tuna preservation on the Andalusian Atlantic coast grew around the almadraba fisheries and older Mediterranean salting traditions. Removing the loin, salting and drying it created a dense food that could travel far beyond the fishing season. Today the names Mojama de Barbate and Mojama de Isla Cristina are separately protected, while generic mojama continues to describe salt-cured tuna loin made elsewhere.

Name. From the Arabic musama, meaning dry or cured.

Production today
Made in Cadiz (Barbate, Conil), Huelva (Isla Cristina) and Murcia.
Protection
PGI for Mojama de Barbate (2015) and Mojama de Isla Cristina (2016).
Tradition vs modern
Traditional almadraba tuna and wind-drying; industrial versions dry faster and taste of it.
Seasonality

Serving and cultural significance

Slice the tuna paper-thin and dress it with olive oil, toasted almonds and tomato, or serve it with oranges and bread. The cured loin is intensely savoury, so small portions are enough. Refrigerate the cut piece and protect it from drying.

Notes

  • The official protected specification controls the named product. Any Curesmith EQ, starter-culture, curing-salt or home-scale adaptation is a separate method and must not be presented as designation-compliant.
  • A more efficient way of curing this product is using the EQ Method. No more than 2.5% salt to meat weight is required. To follow the EQ method, please use our whole-muscle EQ curing calculator to work out proper ratios and curing times.
  • The salt-box figures here are packing amounts, not uptake; the PGI product finishes at 3 to 9% salt and 40 to 50% moisture after 35 to 45% weight loss.
  • Fish safety differs from meat; follow the FDA Fish and Fishery Products guidance for histamine and Listeria control.

Safety. A cured fish, not a meat; manage histamine by using very fresh, well-chilled tuna and follow fish-specific guidance.
