01 - Combine green cabbage, red cabbage, carrot, mayonnaise, apple cider vinegar, honey, salt, and black pepper in a large mixing bowl. Toss thoroughly until evenly coated and cover. Refrigerate while preparing the shrimp.
02 - Pour vegetable oil into a deep skillet or Dutch oven to a depth of 2 inches. Heat to 350°F, monitoring temperature for accuracy.
03 - In a separate mixing bowl, whisk together flour, cornstarch, baking powder, smoked paprika, garlic powder, salt, and black pepper. Gradually incorporate cold lager, whisking until a smooth batter forms.
04 - Pat shrimp dry using paper towels and lightly coat with flour. Working in batches, dip each shrimp into the beer batter, allowing excess to drain.
05 - Carefully lower battered shrimp into hot oil. Fry for 2 to 3 minutes, turning once, until golden and crisp throughout. Remove with a slotted spoon onto a plate lined with paper towels. Repeat until all shrimp are cooked.
06 - Divide slaw evenly among warmed tortillas. Top each with 3 to 4 shrimp. Garnish with cilantro, jalapeños, lime wedges, and hot sauce as desired. Serve promptly for best texture.
