This is a half order of parpatana of tuna...with curried coconut sauce...the parpatana is a very fatty cut of the fish, located between the head and the belly..somewhere in there !!! I doubt if you would find this cut outside Spain and even then, not outside restaurants in this area and in Madrid...(Maribel will know more!!). If you see it on a menu--order it..you have not had any part of any fish that tastes anything like this one.....outstanding!!! Can this really come from the sea????
