Combine all the marinade ingredients in a deep bowl that can submerge the chicken drumsticks. Marinate for 3-4 hours in the fridge, turning once or twice to ensure the chicken marinates evenly.
When ready to fry the chicken, bring the drumsticks out to warm up a little- about 30 minutes before cooking. Choose a thick-bottomed skillet or dutch oven for frying. Heat the rendered fat to 350 degrees using a thermometer to maintain the temperature.
Dip each drumstick in the seasoned flour and coat fully. Once all drumsticks are dredged, gently lower into the hot fat and cook for 10-15 minutes or until the internal temperature has reached 160 degrees.
Drain the drumsticks on paper towels and season with thyme, lemon zest and salt and enjoy!
