Atria Drumsticks are easy to prepare in a variety of ways. Unseasoned chicken drumsticks are Finnish chicken. Take the drumsticks into room temperature 30 minutes before cooking. Place the drumsticks evenly on an oven tray lined with baking paper and bake at 175°C (standard oven) for about 45 minutes until the internal temperature reaches 75°C. The antibiotic-free label on the package shows that the animals have not had any antibiotics during their lifetime.
