Toast the salt cod over a flame or under the grill until it is lightly browned and softened. Put it in a bowl of water while preparing the remaining ingredients. Arrange the orange and onion slices on a plate. Whisk the garlic with the oil, vinegar and red pepper flakes. Drain the cod and remove all skin and bones.

Semana Santa, like any other festival, has its own special flavours and this is especially during this week because traditionally Catholics are not supposed to eat meat. A great time for seafood.
