Heat about 2.5 cm of vegetable oil in a deep skillet over medium-high heat. The oil is ready when a small amount of coating sizzles upon contact. Fry the cod fillets in batches for about 3-4 minutes on each side, or until golden brown and crispy. Remove with a slotted spoon and place on paper towels to drain excess oil.
