Place the 3 pounds of separated chicken wings in a large bowl and sprinkle with 2 tablespoons Cajun seasoning; toss to coat. Cover and refrigerate for 30 minutes to marinate.
In a separate bowl, whisk together 2 large eggs, 1/4 cup low-fat milk, and 2 dashes hot sauce until smooth.
In a shallow bowl or pie plate, combine 2 tablespoons cornstarch, 2 cups all-purpose flour, and 1 teaspoon seasoning salt; mix well.
Working in batches, dip each marinated wing into the egg mixture, letting excess drip off, then coat thoroughly in the flour mixture. Shake off any excess flour.
Heat 3 cups vegetable oil in a deep pan or Dutch oven over medium-high heat until it reaches 350°F (use an instant-read thermometer to check).
Fry the wings in batches without overcrowding the pan for about 5 to 7 minutes per batch, until golden brown and cooked through (internal temperature 165°F).
Use tongs to transfer the cooked wings to a paper towel–lined plate to drain briefly, then serve hot.
