1In a large pan( I use a 12" cast iron dutch oven). combine every thing but the fish. Simmer on med-low heat for 15-20 min. Lay your fish into the liquid cover and simmer 10-15 min Or till fish flakes.
2Carefully remove fish from pot and lay on a plater.
Now combine 2 tablespoons of melted butter and 3 tablespoons flour with 1 1/2 cups of liquid from pot. Cook in a sauce pan till thickened. Pour over fish and serve.
