Brown Fish Stew

2 lbs. large fish (snapper, etc)
1 onion (sliced)
1 tbsp. butter
1 tbsp. flour
water or stock (to thicken)
salt & pepper (to taste)
oil for frying

Prepare the fish cutting it crosswise in 1" thick slices. Fry it lightly. Make brown sauce by frying onions in butter and adding flour slowly until brown. Add enough water or stock to thicken, add salt and pepper to taste. Place the fish in a deep frying pan and pour the brown sauce over the fish. Allow to simmer for about 15 minutes, turning the fish once. Serve hot alone, over peas & rice, white rice or pasta.
