I find strange the spanish Mackerel: if it were today with globalization and the fact that some species which were popular are now on the way to extinction so the market is flooded with fish from far away and remote regions i could understand, but this is probably from around 1990 or older., it was hard to get exotic ingredients and sea and ocean fish species were still plentiful back then, in many more cases.
Those wide slices of octopus make me think if ti won't be a giant squid instead. Never seen an octopus tentacle more than half as wide, even though it is very common around here and in the last 20 years we get them from many other areas in the world too.
