This is a very unique Portuguese Salt Cod fish dish. Very popular in the Azores Islands of Portugal. Cooked for many occasions and well enjoyed. To save yourself time you can prepare the potatoes ahead of time and let them soak in water untill you are ready to start your dish. Also please note, the Cod must be soaked in water overnight. However if you miss this step you can boil the Cod in a pot of water and keep changing the water a few times. This is to remove the salt from the Cod. Use Boneless Salted Cod (not frozen). You can find this in many Super Markets. I have mentioned below that you can also use a Food Processor and shred the potatoes and onion for ease. You can also cheat by using a family size bag of shoestring french fries ;) Prep time does not include soaking of the Cod.
