Prepare the fish by cutting it into 1" strips, patting dry with paper towel and dusting each side with salt.
Heat the oil to 350 degrees using a deep fryer. We like to use a propane deep fryer because it can be used outside and while camping.
In a medium mixing bowl, combine the batter ingredients and allow it to rest for ten minutes. The sparkling water is what creates the light, fluffy texture of the coating.
Dip the fish in the batter, coating it completely and gently place it into the hot oil.
Allow the fish to cook for about 2 minutes per side, rolling the fish half way through cooking so that both sides are a nice golden brown color. Each piece of fish will take about 5 minutes to cook and will need to be cooked in batches, depending on how big your deep fryer is.
Remove the fish from the fryer and place it on paper towel to soak up any excess oil.
Notes
Use fresh fish for the best flavor.
For extra crispy fish, double-dip in the batter before frying.
Don’t overcrowd the fryer, or the temperature of the oil will drop and ruin the crunch.
If you love spice, add a teaspoon of chili powder or cayenne pepper to the batter.
Store leftovers in an airtight container and reheat in a hot skillet for best results.
Make your tacos keto-friendly by using lettuce wraps instead of flour tortillas.
