Tasty cod

Preparation:

Preparation: Boil the potatoes in boiling water for about 30 minutes, then drain them, peel them and cut them into thin slices. Flake the cod and finely chop the parsley and garlic. Arrange the layers of sliced potatoes and cod in a greased baking dish, alternating them and seasoning each layer with a little mince, salt, freshly ground pepper and knobs of butter. Put everything in the oven for about 20 minutes. In the meantime, prepare the béchamel: melt 30 g of butter in a saucepan, add the flour, a pinch of salt; dilute everything with the milk and bring to the boil, stirring constantly. Pour the béchamel sauce over the cod and put it back in the oven for another 15 minutes or until a golden crust has formed on the surface of the preparation.
