In a large bowl, whisk the egg. Continue whisking while slowly adding the beer.
In another bowl, combine the flour, baking soda, salt, black pepper, cayenne pepper and garlic salt.
Drizzle the flour mixture into the egg bowl while stirring constantly. Set aside for 30 minutes.
Meanwhile, bring a large pot of salted water to a boil.
Add the wings and boil for 5 minutes.
Drain the wings and transfer to a wire rack-lined baking sheet. Pat dry and set aside until ready to cook.
Bring a few inches of oil to 350 F in a deep fryer or Dutch oven.
Working in batches if needed, add wings to the batter and coat well. Transfer to the oil and fry for about 5 minutes or until golden brown.
Remove to a paper towel-lined plate or wire rack-lined baking dish to drain while cooking the remaining wings.
Serve with malt vinegar and enjoy!
