I always cut the bottom of the drumsticks off to expose the bone, and then slash three cuts across the drumstick/thigh.
Then I use butter mixed with sea salt/fresh ground pepper and some thyme and oregano or a Herb du Province type mix to rub over the skin and in to the cuts, also I�ll make a little nick in the breast skin where it connects to the breast at the cavity opening and put some of the butter mix under the skin along the breast.
Then slug a bit of olive oil on and crumble a chicken oxo cube over the top and in the oven (200C) for an hour(ish) (basing with the cooking juices every 20mins)or until it looks cooked (crispy skin and no blood in the juice when stabbed in the thigh.
Hmmmmmmm�.. then take it out and leave it to rest covered in foil, then with the coking juice heat it up and add a big glass of red wine and reduce for a light gravy (or use some corn flour or flour to thicken)
