Ingredients
  

Ingredients

  • 1 lb firm white fish fillets (cod, haddock, pollock, or halibut), cut into 4–6 pieces
  • 3/4 cup all-purpose flour
  • 1/4 cup cornstarch (or rice flour)
  • 1 1/2 teaspoons baking powder
  • 1 teaspoon kosher salt, plus more for finishing
  • 1/2 teaspoon black pepper
  • 1/2 teaspoon garlic powder (optional)
  • 1/2 teaspoon paprika or Old Bay (optional)
  • 3/4 cup very cold sparkling water or club soda (start with 2/3 cup, add as needed)
  • 1 tablespoon vodka (optional)
  • 1/2 cup flour for dredging
  • Neutral oil for frying (peanut, canola, or sunflower)
  • Lemon wedges, malt vinegar, or tartar sauce for serving

Instructions
 

Instructions

  • Pat the fish fillets very dry with paper towels, trim thin tails for even cooking, season lightly with salt and pepper, and chill while heating the oil.
  • Pour 2–3 inches of neutral oil into a deep pot or high-sided skillet and heat to 350–365°F, adjusting the heat to maintain temperature.
  • In a bowl, whisk together 3/4 cup flour, cornstarch, baking powder, 1 teaspoon salt, black pepper, and any optional spices.
  • Pour in ice-cold sparkling water (starting with 2/3 cup) and vodka if using, and stir gently just until combined, leaving small lumps; adjust with a splash more liquid to reach heavy-cream consistency.
  • Place 1/2 cup flour in a shallow dish and lightly dredge each fillet, shaking off excess.
  • Dip the dredged fish into the batter, allowing excess to drip for 1–2 seconds.
  • Fry the fish in batches without crowding, 3–5 minutes total, turning once, until deeply golden, crisp, and the thickest part flakes easily; keep oil between 350–365°F.
  • Transfer to a wire rack set over a sheet pan, sprinkle with salt while hot, and serve with lemon wedges, malt vinegar, or tartar sauce.

Notes

Start with icy-cold liquid to keep the batter light and crisp; do not overmix. Maintain oil at 350–365°F for best color and minimal grease. For gluten-free, use a 1:1 GF flour blend and rice flour; for beer-battered, swap in cold lager. Reheat leftovers in a 400°F oven or air fryer for 7–10 minutes; avoid microwaving. You can freeze cooked pieces and reheat from frozen at 425°F for 12–15 minutes.
