ginger, grated
1 c shoyu
1/2 c mirin
1 c brown sugar, packed
1 c water
1/2 c sake

In a 5-qt dutch oven, heat oil and brown oxtails on all sides. Add garlic and ginger to pot. Place oxtails with "eyes" facing up. Add shoyu, mirin, brown sugar, water, and sake. Cover and bake in a 300 degree oven for 2 hours. Remove cover and bake 30 more minutes. At this point, oxtails can be refrigerated overnight and hardened fat removed before proceeding, or use a fat separator to remove as much fat as possible. Preheat oven to 350 degrees. Bake covered for 15 minutes or 30 minutes (if chilled overnight). Remove cover and bake 30 minutes more.
