Crispy, golden beer battered fish made with cod and a seasoned batter. This recipe includes a from-scratch tartar sauce that takes 5 minutes to mix. The beer in the batter creates a light, airy coating that shatters on the first bite.
In a small bowl, combine the mayonnaise, sweet relish, 1 tablespoon of milk, lemon juice, fresh dill, Dijon mustard, salt, pepper, and minced garlic. Stir until smooth.
Taste and adjust with more salt and pepper if needed. Add more milk, 1 tablespoon at a time, until you reach your desired consistency.
Cover and refrigerate until ready to serve.
Prepare and Fry the Fish
Heat 2 to 3 inches of canola oil to 375°F in a deep pot or Dutch oven.
Pat the cod dry with paper towels. Cut into 3x5 inch pieces and season all sides with salt and pepper.
In a large bowl, whisk together the flour, Old Bay seasoning, garlic powder, paprika, sugar, and baking powder.
Add the beaten egg and stir it in. Pour in the cold beer and stir just until the batter comes together. Do not overmix. Small lumps are fine.
Test whether the oil is hot enough by dipping a knife in the batter and placing it in the oil. If it bubbles vigorously, the oil is ready.
Dip each piece of cod into the batter one at a time, letting excess drip off, and carefully place it into the hot oil. Fry 3 pieces at a time so they are not touching.
Cook for 3 to 4 minutes, or until the fish is golden brown. If the fish is not fully submerged, carefully ladle hot oil over the top.
Transfer the fried fish to a wire cooling rack set on a foil-lined baking sheet. Sprinkle with salt immediately.
Repeat with remaining fish. Serve hot with the chilled tartar sauce.
Notes
For the crispiest results, keep the beer cold and do not overmix the batter. Small lumps are fine and actually help create a lighter, crispier coating.You can substitute haddock or pollock for the cod. If using frozen fish, thaw completely and pat very dry before seasoning.To keep fried fish warm while cooking in batches, place the wire rack and baking sheet in the oven at 200-250°F.Store leftover fish in a single layer in an airtight container in the fridge for up to 3 days. Reheat in a 400°F oven on a wire rack for 8-10 minutes. The tartar sauce keeps for 3-5 days refrigerated.
