This delicious Spanish Cuca Yellowfin tuna preserved in organic extra virgin olive oil will impress any tuna lover. This is our personal favourite, the EVOO is just beautiful. Cuca tinned seafood products from Spain are so good that acclaimed restaurateur, Frank Camorra (Movida), began importing them himself and uses them in his restaurants. about the producer Cuca have been preserving fish and seafood since 1932. The shallow, fjord like saltwater estuaries – the “Rias” – that face the Atlantic ocean in the north west of Spain produce anchovies, mussels, octopus, tuna, squid and sardines of outstanding quality. Cuca use only the best raw materials, harvest by hand, clean and pack each morsel by hand and use nothing but the raw natural materials, seafood, olive oil and brine. The results are products that retain their natural shape and texture through the tinning process. You can really taste the difference.
