The fish is dried, salted cod. Until fairly recently, this was the standard method of preserving cod. Before preparation, the cod had to be placed in water for at least two days to rehydrate and also leach away the salt. It is recommended to change the water regularly. In this incident drawn from Mark Kurlansky's history The Cod's Tale, a salt cod was placed in the tank of a toilet in the French premier's residence in 1947 before a state dinner, and a valet assigned to regularly flush it.
