Ingredients:

  • 4 (approx. 6 oz each) Cod Fillets (Skinless, center cut, approx. 1 inch thick)
  • 1 tsp Fine Sea Salt
  • 1/2 tsp Freshly Ground Black Pepper
  • 1 cup All-Purpose Flour (divided)
  • 1 Large Egg
  • 1 Tbsp Whole Milk or Buttermilk
  • 1 tsp Smoked Paprika (Sweet or Hot)
  • 1/2 tsp Garlic Powder
  • 1 tsp Lemon Zest (from 1 medium lemon)
  • 1/2 cup High Smoke-Point Oil (e.g., vegetable, canola, or refined peanut oil)
  • 1 Tbsp Unsalted Butter (for finishing, optional)

Instructions:

  1. Dry the Fish: Pat the cod fillets thoroughly dry using paper towels. This is crucial for a crisp crust; moisture is the enemy of crunch.
  2. Season: Sprinkle the fillets generously on both sides with sea salt and black pepper.
  3. Set up Dredging Stations: Arrange three shallow dishes side-by-side. Dish 1 (Binder): Whisk the egg and milk together. Dish 2 (Plain Flour): Place 1/4 cup of the plain flour. Dish 3 (Seasoned Flour): Combine the remaining 3/4 cup flour with smoked paprika, garlic powder, and lemon zest. Whisk thoroughly.
  4. The Double Dusting Technique: Coat each fillet using the following sequence for maximum adhesion: 1) Dust lightly in the Plain Flour (Dish 2). 2) Dip the fillet into the Egg Wash (Dish 1). 3) Press the fillet firmly into the Seasoned Flour (Dish 3) until completely coated.
  5. Rest (Optional): Place the coated fillets on a wire rack for 5 minutes. This allows the coating to hydrate slightly and adhere better during frying.
  6. Heat the Oil: Place a heavy-bottomed frying pan over medium-high heat. Add the high smoke-point oil. The oil is ready when it shimmers slightly and a small sprinkle of flour bubbles immediately upon contact (around 350°F / 175°C).
  7. Fry the First Side: Gently place the cod fillets into the hot oil, ensuring they are not crowded. Fry undisturbed for 4–5 minutes until the bottom crust is deep golden brown and crispy.
  8. Flip and Finish: Carefully slide a fish spatula under the fillet and flip it gently. Reduce the heat slightly to medium. Fry for another 4–6 minutes.
  9. Butter Baste (Optional): In the last minute, add the tablespoon of butter. Tilt the pan and spoon the foaming butter over the fillets repeatedly to enhance flavour.
  10. Drain and Rest: Remove the fish immediately and place it on a wire cooling rack (do not use paper towels). Serve immediately.
