		Notes
		
			
- Substitute cod with haddock or pollock if needed.
- Add cayenne or a dash of hot sauce to the batter for a spicy twist.
- Use a wire rack (not paper towels) to keep everything extra crispy.
- Batter should be made fresh—keep sparkling water chilled until ready to use.
- For a lighter version, try baking at 425°F with a light oil spray.
