What a shame that on an island like Britain most towns do not possess one single fishmonger (let alone a proper food market) and that the supermarkets where most food is bought anyway provide a pathetically small choice of fish, most of it ready filleted or smoked or 'previously frozen'.
The central part of the Jerez covered market is totally devoted to fish. In the stalls around the periphery there are butchers selling a little fresh meat including the odd (wild) bunny and sausages and plenty of preserved meat (in the form of hams and more sausages). There are greengrocers selling notably knobbly fruit and vegetables, nothing too perfectly smooth and shiny like in the UK. The odd frutos seccos shop selling nuts and dried fruit and honey too. And one lone baker selling crap bread, Spain being a curiously bread challenged country. Here, the Brits might have the edge, Sunblest and Hovis notwithstanding.
