Pork roast is generally part of the menu for a big winter meal, like sunday dinners in january in front of a roaring fire. Pork roast can also be cooked to delicious effect on the grill during warmer weather. Long, slow cooking on the rotisserie makes for a juicy, tender roast that's infused with smoky flavor that can't be duplicated in the oven. For barbecue flavor, brush the roast with your favorite barbecue or grill sauce about 10 minutes before it's finished cooking.
