Make the dough by kneading all the ingredients together and leave to rest of 1 hour. Then split into two pieces, one larger than the other. Roll out the larger piece into a thin pastry and place on a greased baking tin. The smaller piece will cover the pie once the filling has been added, and once it has been rolled out into a sheet as well.
Remove the skin and bones from the cod (if needed). Cut the cod fillet into small pieces. Chop the garlic, onion, parsley, tomato, add the tomato puree, marjoram, oil and rice, and mix with water. Place in the baking tin and cover with the second pastry sheet. Sprinkle with a little water, brush the top of the pie with a little oil and water (or with an egg), and bake at 200C for 1 hour.
