Ingredients

Scale
  • 1.5 lbs Cod fillets, skinless and boneless, cut into 2-inch pieces
  • 1 cup All-purpose flour
  • 1/2 cup Cornstarch
  • 1 tsp Baking powder
  • 1/2 tsp Baking soda
  • 1 tsp Salt
  • 1/2 tsp Black pepper
  • 1/4 tsp Garlic powder
  • 1/4 tsp Onion powder
  • 1 cup Cold club soda or sparkling water
  • 1 large Egg, lightly beaten
  • Vegetable oil, for frying
  • 2 large Yellow onions, sliced into 1/2-inch thick rings
  • 1 cup All-purpose flour
  • 1/2 cup Cornstarch
  • 1 tsp Baking powder
  • 1/2 tsp Salt
  • 1/4 tsp Black pepper
  • 1 cup Cold milk (or buttermilk for extra tang)
  • Vegetable oil, for frying
  • 1/2 cup Mayonnaise
  • 2 tbsp Ketchup
  • 1 tbsp Sweet pickle relish
  • 1 tsp Dijon mustard
  • 1/2 tsp Paprika
  • Pinch of cayenne pepper (optional)

Instructions

  1. Prepare the Cod: Pat the cod pieces dry with paper towels. Season with salt and pepper.
  2. Combine Cod Dry Ingredients: In a large bowl, whisk together flour, cornstarch, baking powder, baking soda, salt, pepper, garlic powder, and onion powder.
  3. Prepare Cod Wet Ingredients: In a separate bowl, whisk together cold club soda (or sparkling water) and the lightly beaten egg.
  4. Combine Cod Wet and Dry Ingredients: Gradually pour the wet ingredients into the dry ingredients, whisking constantly until just combined. Be careful not to overmix! A few lumps are okay.
  5. Batter the Cod: Dip each piece of cod into the batter, making sure it’s fully coated. Let any excess batter drip off before placing it into the hot oil.
  6. Prepare the Onions: Slice the onions into 1/2-inch thick rings. Gently separate the rings.
  7. Combine Onion Rings Dry Ingredients: In a large bowl, whisk together the flour, cornstarch, baking powder, salt, and pepper.
  8. Prepare Onion Rings Wet Ingredients: In a separate bowl, pour in the cold milk (or buttermilk).
  9. Batter the Onion Rings: Dip each onion ring into the flour mixture, ensuring it’s fully coated. Then, dip it into the milk (or buttermilk), and finally, back into the flour mixture.
  10. Heat the Oil: Pour vegetable oil into a large, heavy-bottomed pot or deep fryer until it’s about 3 inches deep. Heat the oil over medium-high heat to 350°F (175°C). Use a thermometer to monitor the temperature.
  11. Fry the Cod: Carefully lower the battered cod pieces into the hot oil, working in batches to avoid overcrowding the pot. Fry for 3-4 minutes per side, or until golden brown and cooked through. The internal temperature of the cod should reach 145°F (63°C).
  12. Fry the Onion Rings: Carefully lower the battered onion rings into the hot oil, again working in batches. Fry for 2-3 minutes per side, or until golden brown and crispy.
  13. Drain the Excess Oil: As the cod and onion rings are cooked, remove them from the oil with a slotted spoon and place them on a wire rack lined with paper towels to drain the excess oil.
  14. Combine Dipping Sauce Ingredients: In a small bowl, whisk together the mayonnaise, ketchup, sweet pickle relish, Dijon mustard, paprika, and cayenne pepper (if using).
  15. Adjust Dipping Sauce to Taste: Taste and adjust the seasonings as needed.
  16. Chill Dipping Sauce (Optional): For best results, chill the dipping sauce in the refrigerator for at least 30 minutes to allow the flavors to meld.
  17. Serve Immediately: Serve the crispy battered cod and onion rings immediately while they’re still hot and crispy.
  18. Garnish (Optional): Garnish with a sprinkle of fresh parsley or a squeeze of lemon juice for added flavor and visual appeal.
  19. Serve with Dipping Sauce: Serve with the optional dipping sauce for dipping.
  20. Enjoy! Dig in and enjoy the delicious combination of crispy cod, sweet onion rings, and tangy dipping sauce!

Notes

  • Patting the cod dry is crucial for crispy batter.
  • Cornstarch is key for a light and crispy batter for both the cod and onion rings.
  • Don’t overmix the batter. A few lumps are okay.
  • Use cold club soda (or sparkling water) for a light and airy cod batter.
  • Buttermilk adds a nice tang to the onion rings.
  • Double-dipping the onion rings creates an extra-thick and crispy coating.
  • Maintain the oil temperature at 350°F (175°C) for optimal frying.
  • Don’t overcrowd the pot when frying.
  • Drain excess oil on a wire rack lined with paper towels.
  • Chilling the dipping sauce allows the flavors to meld.
