This is a favorite recipe on the boat. Usually prepared this way, the
first fresh fish we get unless the weather is too nasty. Take the
appropriate sized casserole dish and rub thickly with full fat cream cheese.
Take the halibut fillets that you have trimmed to be of equal width
(thickness). Next spread sour cream over the fish and sprinkle sauteed
onion (in olive oil and vermouth) over the fish.. You can simply cover with
tin foil and bake at 400 ( ten minute per inch) or for a more elegant
presentation use a phyllo dough cover.
