Cod, or what's called Tørsk, is something i have eaten at least 3x a week in Norway, for 26-years. In Norway, it is used a lot to make Fiskerkaker (Fishcakes). Every store, every supermarket, and every fish market sells cod either salted (what you guys call Bacalao), or fresh, or as Fiskerkaker. It's so common that i literally survive on it because i do not cook, so i simply buy either 20-packs of fiskekaker or smoked salmon---its the lazy man's way of eating on the run. Again, i don't cook.
On a side note, my father, who grew up in Bonao in the 1930 & 40's, grew up eating Babaclao (As did my Dominican grandfather as well), and the reason is simple...there were no refrigeration back when my father and grandfather were growing up. Hence, Bacalao is salted, and therefore, it never spoiled. It's been imported into the DR forever.
I really highly recommend to read Mark Kurlansky's biography of "Cod, A biography of the Fish that Changed the World."
It literally changed the world, and the book is riveting. Navy's and lots of other things exist today, would not have grown at the speed and level that they did without Salted Cod.
History fans will not put this book down until they finish it. I would follow this book with the history of "Salt"...another fascinating history by the same guy. When Mark was writing about the history of Salt, that lead him to write about Cod, once he realized that they were related throughout history.
By the way, i have dozens of photos of fresh Cod in Norway. It's everywhere.
