Instructions

1. Step 1: In a small bowl, combine 1/2 cup thinly sliced red onions, 1/4 cup white vinegar, 1/4 cup water, 1 teaspoon sugar, and 1/4 teaspoon salt; stir until sugar dissolves and let stand at room temperature for 15 minutes to pickle.
2. Step 2: Whisk 1/2 cup sour cream, the zest and juice of 1 lime, 1 tablespoon chopped cilantro, and 1/4 teaspoon salt in a small bowl until smooth and emulsified.
3. Step 3: In a small bowl, mix 1 teaspoon chili powder, 1/2 teaspoon ground cumin, 1/2 teaspoon garlic powder, 1/4 teaspoon salt, and 1/4 teaspoon black pepper. Pat 1 pound walleye fillets dry with paper towels, then coat evenly with the spice mixture.
4. Step 4: Heat 2 tablespoons olive oil in a large skillet over medium-high heat until shimmering. Add the seasoned walleye in a single layer and cook for 3-4 minutes per side, until golden brown and the fish flakes easily with a fork.
5. Step 5: Warm 8 corn tortillas in a dry skillet for 15-20 seconds per side until pliable and lightly charred.
6. Step 6: Assemble tacos: Place 2-3 pieces of cooked walleye on a warm tortilla, top with 1 tablespoon pickled red onions and 1 tablespoon lime crema, and serve immediately.
