Put the drumsticks in a large bowl, add lemon juice and one teaspoon of salt and rub it all over the drumsticks. Cover and marinate for at least 3 to 4 hours.
Beat the egg and milk in a bowl. Combine the bread crumbs, corn flakes, sesame seeds, salt, pepper, chilli powder and garlic powder in a plastic bag. Dip the drumsticks in the egg mixture, then shake in the bag to coat. Preheat the oven to 450 degrees.
Grease a baking sheet. Arrange the coated drumsticks on a greased baking sheet and drizzle with the melted butter. Bake for 25 to 30 minutes. Serve immediately.
