but i finally tracked some down at the family fisheries on campobello, island! it's simply dried fish cured in salt brine that i guess is sort of like fish jerky. some might claim that you can't find it anywhere because it's nasty and somethign that only old fisherman can appreciate. but not me! i love the stuff.
in addition to finding a rare favorite food, i also enjoyed the best ( and cheapest ) plate of fried clams that i've had in my entire life in the humble family fisheries restaurant. if you're in the area you owe it to yourself to stop on by and some great seafood.
