Rinse the chicken and pat it dry with paper towels. Add the ginger and garlic to the chicken and gently rub them in. Then, add the remaining ingredients and stir to mix well, ensuring the chicken drumsticks are evenly coated.
Set aside to marinate for at least 30 minutes, or up to 2 hours in the fridge for the best results.
Preheat the oven to 375°F (190°C). Arrange the chicken on a baking sheet lined with parchment paper and bake for 30-40 minutes in the middle of the oven, or until the surface is golden brown and slightly charred, and the inside is cooked through. Serve warm.
