Marinate longer up to 4 hours for juicier chicken but not longer to avoid mushiness. Use a wire rack to prevent sogginess after dredging. Maintain oil temperature at 350°F for crispiness. Fry in batches to avoid overcrowding. Lightly butter buns before toasting for extra richness. Use fresh pickles for authentic flavor. Variations include spicy version by adding cayenne or hot sauce, gluten-free flour substitute, grilled option, different buns, and dairy-free alternatives.
