In a large cast iron skillet, pre-heat oil temperature to 350°F.
Wash and towel dry cod, then season with a pinch of sea salt and pepper; set aside.
In a large bowl, add all the spices and flour, ketchup, egg then stir in beer.
Place all cod pieces in the beer batter and equally coat with batter.
Slowly place two pieces of cod in the vegetable oil; this will stop the batter from sticking to the grill in the fryer.
Fry cod for 5 minutes on each side until golden brown, then remove.
Place on rack with paper towel on the bottom to soak up oil.
Continue until all cod pieces are deep fried.
