Pat dry the drumsticks. Trim off excess skin and any loose bones/tissue especially in the joint area.
Now preheat grill to get a surface temp of about 450. That is medium high on a standard gas grill and medium on a hotter gas grill. Clean and oil.
Mix spices. 1 T kosher salt, one t pepper and garlic powder and 1/2 t cayenne pepper.This is more than you need. Keep it for next time. You can also use my 7:2:2 spice mix. You may want to skip the cayenne if cooking for little ones. Or use seasoning of your choice.
Lightly sprinkle chicken on all side to taste. Let rest at room temperature until grill is ready.
Check grill temp if possible and place chicken on the grill.
Flip every 5-7 minutes until internal temp of 185-190 degrees. About 30-35 minutes.
Let rest for 10 minutes before serving. They are way too hot anyways.
