In a large container, mix together the mayo, milk and spices. Add the chicken drumsticks then stir or shake to coat. Marinate for 30 minutes.
Coat each drumstick in the cornflakes, then place in an air fryer. Give them a light spray of oil.
Air fry for 18-20 minutes at 180°C until golden and cooked through. Serve with mashed potato, gravy and peas.
