There was a wonderful Calvin Trillin article* recently in the New Yorker about a rich Ecuadorean stew called "fanesca." Although it is a dish associated with the Lenten period, it could easily be made kosher, since it's just vegetables, milk/cream and salt cod. But...
Can one purchase kosher salt cod?
I've never looked, but I don't picture it being something you can walk into a kosher fish shop to get. Not that I frequent kosher fishmongers, either. I couldn't find any information whatsoever online, though I did find a few places that sell and ship salt cod.
Anyone have any ideas in Manhattan or Brooklyn?
It seems like it would be a good ingredient to use in any number of dishes, Jewish and otherwise. The (Philadelphia) Jewish Exponent listed a recipe for Pasticcio di Baccala e Spinaci allUso Fiorentina
(Florentine Gratin of Salt Cod and Spinach) that looks good, too. (http://www.jewishexponent.com/ViewArt...).
