Here is a version of this classic and easy recipe to follow at home. It is popular in Livorno, Tuscany.
500 g canned tomatoes
650 g salt cod, soaked and drained
Plain flour for dusting
100 ml olive oil
A bunch of parsley chopped
I garlic clove chopped
Salt and pepper
Whizz the tomatoes into a puree in the food processor. Cut the cod into chunks and coat lightly with flour. Heat the oil in a large frying pan and cook the cod until lightly browned on both sides. Add the tomatoes and salt and pepper. Cook for a few minutes so the cod soaks up the flavours. Then sprinkle with the chopped garlic and parsley. Cook for 5 minutes and then serve. It goes well with rice or new potatoes.
