I had this while on holiday on the island of Sal, of the Cape Verde islands in October 2007. As an ex-Portuguese colony the Portuguese influences are strong. We found this recipe so delicious I had it several times while I was in Cape verde and enjoyed several attempts at making it at home as soon as we got back. This tastes pretty close to the original. If you can possibly use dried salt cod, then please do, the flavour is definitely superior to average ordinary white fish. As usual with salt cod, no additional salt is needed in the recipe, it will be salty enough. For instructions on how to deal with your dried salt cod, I recommend this recipe by Julesong: Recipe #242753. My recipe time assumes that you have soaked and cooked your salt cod already and that you've taken out the bones, so it's flaked and ready to go. I usually hard boil the eggs in the same water with the potatoes and remove them with a slotted spoon once I figure that they have had enough time to have hard boiled. Saves using an extra pot! This can be made a day in advance but more time than stated would be needed in the oven to heat it though.
