Notes
Whitefish and Pike come from freshwater lakes in Nova Scotia, Canada and usually need to be ordered.Ask your fishmonger to clean the fish and separate the trimmings from the fillets.A good fishmonger will clean the fish thoroughly, but to be on the safe side, check to make sure no bones are left in the fillets.
