How to Make It
Place fish in a large heavy-duty zip-top plastic bag. Combine 12 ounces beer and Mexican seasoning in a bowl, stirring well. Pour beer mixture over fish; seal. Chill 2 to 3 hours.
Pour oil to depth of 1 1/2 inches into a deep skillet or Dutch oven; heat to 360°.
Combine flour and next 3 ingredients in a medium bowl. Whisk in 1 cup beer and hot sauce. Drain fish, discarding marinade. Coat fish in batter.
Cook fish in batches about 4 minutes or until done. Drain on paper towels.
Place 2 to 3 pieces of fish on each tortilla. Squeeze lime wedges over fish; top with remaining ingredients. Serve immediately.
