Fried Fish Fillets (Kızarmış Balık)

2 lbs cod fillets (or any other fish fillets)
3/4 cup flour (whole wheat)
6 tbsp olive oil
2 tbsp salt or as much as it takes for all the fillets
2 tbsp ground black pepper
2 tbsp marjoram

Wash and dry fish fillets. Sprinkle salt, pepper and marjoram on both sides of the fillets. Spread the flour in a plate. Place each fillet in the flour plate on both sides to make sure they are covered with flour. Heat olive oil 2 tbsp at a time in a large skillet. For each batch, use 2 tbsp of olive oil. I ended up with 3 batches so I used 6 tbsp of olive oil in total. When the oil is hot, put the fish in the skillet. Do not crowd. Put 3-4 fillets at a time if you are using a large skillet. Turn when the bottom of the fish takes a golden brown color. Cook until the other side is also golden brown. Serve with lemon wedges.
