Working in batches of 2-3, dip the cod filets into the beer batter, allowing any excess batter to drip off.
Carefully lower the battered fish into the hot oil and fry for 5-6 minutes, or until deep golden brown and crispy. Remove the fish with a slotted spoon or tongs and drain on paper towels. Repeat with the remaining fish.
Serve the beer-battered fish with fries, lemon wedges, malt vinegar, ketchup, tartar sauce, and a sprinkle of fresh parsley. Enjoy!
