1 cup cold sparkling water (or beer for extra crispiness)
Instructions
Combine dry ingredients: In a large bowl, whisk together the flour, cornstarch, baking powder, salt, pepper, and any optional spices.
Add liquid: Gradually whisk in the cold sparkling water or club soda until the batter is smooth and lump-free. Don't overmix. A few small lumps are okay.
Chill (optional but recommended): Let the batter rest in the refrigerator for at least 30 minutes. This allows the gluten to relax and helps the batter adhere to the fish better.
Prepare fish: Pat the fish fillets dry with paper towels. This helps the batter stick.
Coat and fry: Heat your frying oil to 350-375°F (175-190°C). Dredge each fish fillet in the batter, ensuring it's fully coated. Let any excess batter drip off. Carefully lower the coated fish into the hot oil.
Fry: Fry the fish for 3-5 minutes per side, or until golden brown and cooked through. The exact cooking time will depend on the thickness of the fish.
Drain and serve: Remove the fried fish from the oil and place it on a wire rack or paper towel-lined plate to drain excess oil. Serve immediately.
Notes
Make Ahead: The batter can be mixed ahead and stored in the refrigerator for up to 24 hours. Stir before using.
Customizing the Flavor: Add a pinch of paprika, cayenne, or garlic powder for extra flavor. For a beer batter, substitute water with your favorite light beer.
Serving Suggestions: This crispy batter works well with cod, haddock, or tilapia. Serve with tartar sauce, lemon wedges, or coleslaw for a classic touch.
Allergy-Friendly Options: Use gluten-free flour for a gluten-free version. To make it egg-free, replace eggs with carbonated water for a light, airy texture.
Storage Tips: Best enjoyed fresh, but leftovers can be stored in the fridge for a day. Reheat in an oven or air fryer for crispiness.
