Heat your oil in a pot on medium-high heat until it registers 350 degrees.

Add the dry ingredients to a mixing bowl and stir to combine everything. Once everything is combined, mix in the cold beer, and lightly whisk until you have a smooth batter.

Let the batter rest for about 5 minutes.

Once the oil is heated, submerge your fish fillet into the batter to lightly coat, and raise it out to let any excess batter drip back into the bowl.

Carefully place this fish fillet into the oil, and cook until you have a nice golden brown, roughly 4-6 minutes. Remove with your kitchen spider, or large slotted spoon, and place on a paper lined plate to remove any excess oil.

Season with a pinch of salt, and repeat.

The end result is a crisp batter that is just a perfect pairing with your fish. Feel free to use on cod or halibut as well.
