It's simple. Make a marinade from the zest and juice from one orange. Add grated ginger - about a tablespoon. Add two garlic cloves, minced. Add a tablespoon or so of Japanese soy sauce, and about the same amount of neutral oil. And a small splash of sesame oil.
Marinate about one kilo of chicken legs in this, for about an hour. Then bake at 200 degrees for about 30 minutes, turning about half way through.
