Frugal Friday Fish

We always seem to eat fish on a Friday.  I'm not quite sure why; it's certainly not a religious thing, but probably reflects that Friday is the day when the fishmonger has the best stuff on his slab.  Anyway, we were spoiled rotten living in Devon, having such good fresh fish right on the doorstep.  It was wonderful to be on such good terms with the guys in the fish market that they would keep back a hake for me, knowing that I would always buy it if they had one.  But more often than not, the Spanish would have snaffled all the hake before it got beyond the wholesale market.  So we'd slum it with line caught mackerel or stiff fresh sea bass.
