Preheat oven to 450°F.
Season the pork with salt, pepper and garlic, if it is not already seasoned. Do not be afraid to season heavily, since this will help to create your gravy.
Place meat roasting pan in preheated oven and begin to roast for 15 minutes.
Turn oven down to 325°F.
For a roast weighing 5-8 lbs, cook for 3 to 4 hours.
For a roast weighing 10-14 lbs, cook 4 to 5 hours.
Baste roast every 45 minutes with a cup of cold broth or water.
Always be sure to check internal temperature with a thermometer. Ovens will vary, causing cooking times to vary as well.
Internal temperature should be 165°F.
