When I was 10 - 12 yrs old ( and up to 18 yrs old) I had a job in a fishmongers ( you dont see them anymore) and on a daily basis I'd fill a cast iron bath with water and brine all the cod and haddock fillets and at the end of the day I'd put them on the poles and stack them in the smoker, put a few shovel fulls of oak dust at the bottom of it light it and then empty it the following day ( on school holiday that is), learnt so much about fish, cleaning , filleting them, smoking them, skining them along with all other things that go with fishmongering, Oh the old days
