I buy the frozen packaged cod that is individually wrapped. I use two pounds. 1/4 cup butter 2/2 cup grated Parmesan cheese 1 cup sour cream
Defrost fish in fridge. Place fish in a baking dish . Melt butter in saucepan..then stir in cheese and sour cream. Pour over fish and bake at 400 degrees for about 15 to 20 minutes. I put paprika and parsley on top for color. Easy and good..
