Heat oil in a saute or saucepan over medium heat. Add shallots and saute until lightly browned.
Add garlic, rosemary, and salt. Cook for a few minutes. Add wine and honey to the pot. Bring to a boil, then reduce heat to low and simmer for 20 minutes until slightly reduced.
Add meat to a large roasting or baking pan, bone side down. Season with salt and garlic powder. Pour sauce over meat. Cover very well. Bake for 4 hours. This freezes very well. Simply return to oven until warm.
