Preheat oven to 375 degrees.
Pat the pork dry and set aside.
Make the dry rub by mixing all the spices in a small bowl. Rub the pork liberally with all the spice. Set aside.
Next make the Honey Garlic Glaze. In a small bowl mix the glaze ingredients. Set aside.
Add 2 Tbsp. olive oil and heat a heavy bottomed skillet to medium high heat. You want it nearly smoking, but not so hot it burns the spices. Sear the meat for about 3 to 5 minutes on all 4 sides until a nice, deep brown crust is formed. Position the pork fat side up.
Brush the Honey Garlic Glaze over the pork. Add the 4 sprigs of rosemary and roast for 25 minutes. Baste the pork every 10 minutes or so with the glaze. 
Tent the pork with aluminum foil and continue roasting for another 20 to 25 minutes or until the temperature reaches 140 degrees. 
Remove from the oven and keep the foil on for 10 more minutes while the pork rests.
