Sprinkle one tablespoon of lemon juice over the cod fillets and set aside for 15-30 minutes.
In a shallow bowl, mix all seasoned flour ingredients. Dredge the fish in flour, shaking off excess.
Heat olive oil and butter in a cast iron skillet over medium-high heat. Cook cod for 5-6 minutes per side until golden brown.
Remove fish to a serving dish. In the same pan, cook garlic and capers for 30 seconds. Deglaze with vermouth, boil for 1 minute, then add remaining lemon juice and parsley. Boil again and pour over fish.
