Crush the pretzels into a fine powder using a food processor or rolling pin.

In a medium bowl, whisk together the eggs, evaporated milk, and beer or club soda.

Dip each fish fillet into the egg mixture.

Place the dipped fillet into the bag of pretzel powder.

Shake the bag to thoroughly coat the fish with pretzel crumbs.

Heat 1/8 inch of olive oil in a 12-inch skillet over medium heat.

Carefully place the coated fillets into the hot oil.

Fry for 3-6 minutes on each side, or until golden brown and cooked through.

Remove the fried fillets and drain them on a paper towel-lined plate.

Serve immediately with lemon wedges for squeezing.
