Soak the salted cod in about 2 litres of water, changing the water 3 times over the course of 8 hours. Drain and cut the fish into bite-size pieces.
Layer the half of each ingredient in the following order: potatoes, cod fish, onions, hard-boiled eggs, capers, garlic, olives, roasted red peppers and raisins. Place the bay leaf on top, then pour half the passata and half the olive oil. Repeat with the remaining ingredients in the same order. Pour the water and white wine on top. Do not stir.
Cover and bring to the boil over medium heat. Reduce heat to medium-low and simmer until the potatoes are tender, about 30 minutes.
Can be found in Mediterranean or Carribean speciality shops.
Alternatives to cod:
Try this recipe with inexpensive fresh coley or pouting. They both belong to the cod family but are much cheaper and available in larger supermarkets or fishmongers.
Excellent tasty recipe! I didn't put the raisins in - didn't fancy them, but added Guindillas (Spanish hot peppers). I may be wrong but thought that saying "Ready in 9 hours 15 mins" may put people off from cooking it and it's more accurate to say "1 hour 15 mins plus soaking of salted cod" - which I soaked for 48 hours, changing water 3 times each day. We did have to add a bit of salt on serving, but that's easier than it being over salty. I will definitely be making this again! Muchas gracias! - 30 Apr 2015
