2 lbs skinless cod fish fillets, making sure all bones are removed
2 ounces butter

1/2 liter milk
5 ounces grated cheese
4 cups mashed potatoes

Place cod fillets in the bottom of a 8x8x2 buttered oven dish.Place dish on a cookie sheet pan because there will be sauce that escapes and runs down the outside of the casserole dish.
Make a cheese sauce by mixing 2 oz each of butter and flour, 1/2 liter of milk and 3 1/2 oz grated cheese cook till slightly thickened: pour over fish.
Top with mashed potatoes sprinkle grated cheese over them and dot with butter.
Bake in a hot oven (450 F) for 25-30 minutes, until the potatoes are golden brown.

Optional -- 1/2- 1 cup peeled and deviened Shrimp added unto the fish gives some added flavor as well!
