Were the drumsticks coated with flour, or cornmeal, and seasoned, or just cooked with seasonings.
If it was the former, You might try this:
Combine 1 cup of all purpose or whole wheat flour with:
2 tsp. granulated garlic
3/4 tsp. crushed rosemary
1/2 tsp. dried basil
1/2 tsp. dried oregano
2 tsp. granulated onion
1 tbs. black pepper
2 tbs. chicken soup base
1 tsp. rubbed sage
1/2 tsp. dried Thyme
1/2 tsp. cayenne pepper (optional)
Whisk until all is completely mixed. Dredge the drumsticks in the seasioned flour mixture, and place on your skewers. Bake, broil, or barbecue until the meat reaches a temperature of 160' F. and the skin is crispy.
If the meat was simply seasoned, try a combination of rosemary, salt, black pepper, granilated garlic, and rubbed sage. Mix them together in a bowl, and dust them all onto the chicken. Skewer and bake, broil, or barbecue the same as above.
