Ingredients

Scale

Main Ingredients:

  • 1.5 lbs Cod fillets
  • 2 large Yellow onions

Batter Ingredients:

  • 2 cups All-purpose flour
  • 1 cup Cornstarch
  • 1 large Egg
  • 1 cup Cold club soda
  • 1 cup Cold milk
  • 1 tsp Baking powder
  • ½ tsp Baking soda
  • 1 tsp Salt

Seasoning and Sauce Ingredients:

  • ½ tsp Black pepper
  • ¼ tsp Garlic powder
  • ¼ tsp Onion powder
  • ½ cup Mayonnaise
  • 2 tablespoons Ketchup
  • 1 tablespoon Sweet pickle relish
  • 1 teaspoon Dijon mustard
  • ½ teaspoon Paprika
  • 1 Pinch cayenne pepper
  • Vegetable oil, for frying

Instructions

  1. Dry cod pieces thoroughly with paper towels. Season each 2-inch piece with ¼ tsp salt and ⅛ tsp black pepper.
  2. Whisk 1 cup flour, ½ cup cornstarch, 1 tsp baking powder, ½ tsp baking soda, 1 tsp salt, ½ tsp black pepper, ¼ tsp garlic powder, and ¼ tsp onion powder in a large mixing bowl.
  3. In a separate bowl, combine 1 cup cold club soda and 1 lightly beaten egg. Whisk gently until blended.
  4. Pour wet ingredients into dry ingredients. Mix until just combined, keeping some small lumps in the batter.
  5. Dunk each cod piece completely in the batter. Allow excess to drip off before carefully placing into the oil.
  6. Slice 2 large yellow onions into ½-inch thick rings. Gently separate the rings with your fingers.
  7. Mix 1 cup flour, ½ cup cornstarch, 1 tsp baking powder, ½ tsp salt, and ¼ tsp black pepper in a wide bowl.
  8. Pour 1 cup cold milk into a separate shallow dish for dipping.
  9. Coat each onion ring first in flour mixture, then dip in milk, then return to flour mixture for complete coverage.
  10. Fill a heavy-bottomed pot with 3 inches of vegetable oil. Heat to 350F using a cooking thermometer.
  11. Drop battered cod pieces into hot oil in small batches. Fry 3-4 minutes per side until golden brown and internal temperature reaches 145F.
  12. Carefully place battered onion rings into oil. Fry 2-3 minutes per side until crispy and golden brown.
  13. Remove fried items with a slotted spoon. Place on a wire rack lined with paper towels to drain excess oil.
  14. Whisk ½ cup mayonnaise, 2 tbsp ketchup, 1 tbsp sweet pickle relish, 1 tsp Dijon mustard, ½ tsp paprika, and a pinch of cayenne in a small bowl.
  15. Taste sauce and adjust seasonings as needed. Refrigerate for 30 minutes to blend flavors.
  16. Serve cod and onion rings immediately while hot and crispy. Sprinkle with fresh parsley if desired.
  17. Place dipping sauce in a small serving bowl alongside the fried items.

Notes

  • Pat the cod dry thoroughly before battering to ensure maximum crispiness and prevent soggy results.
  • Use cold club soda or sparkling water in the batter to create lighter, airier texture that helps achieve extra crunch.
  • Maintain consistent oil temperature around 350F to prevent greasy or undercooked seafood and ensure perfect golden-brown coating.
  • For gluten-free adaptation, substitute regular flour with a gluten-free all-purpose flour blend and verify all other ingredients are certified gluten-free.
