Pat the chicken wings dry with paper towels to remove excess moisture, which helps achieve crispiness during frying.
In a large bowl, combine flour, cornstarch, smoked paprika, cayenne pepper, and a generous pinch of salt. Mix well until evenly blended.
Dredge each wing in the seasoned flour mixture, pressing gently to ensure the coating adheres evenly. Shake off any excess flour.
Heat the oil in a heavy-bottomed pot or deep fryer to 175°C (347°F). Use a thermometer to maintain a steady temperature.
Carefully lower the coated wings into the hot oil in batches, avoiding overcrowding. Fry each batch for about 8-10 minutes, turning occasionally, until the wings are deep golden and crispy with a crackling sound.
Use tongs to transfer the fried wings onto a wire rack lined with paper towels. Let them rest for 5 minutes to allow the skin to crisp further and the juices to redistribute inside.
After resting, check that wings are cooked through (internal temperature should reach 75°C / 165°F). Enjoy immediately, perhaps tossed in your favorite sauce or served plain to appreciate the crispy texture.
