This recipe is based on one from Bon Appetit magazine. It is really delicious and makes the gravy taste terrific. The original recipe calls for a rib roast and cooking for 1 hour. I used pork butt roast and it took closer to 2 hours to cook. I also cut down the garlic a bit, but I think the 6 cloves called for would not be overpowering. I served as a regular roast dinner with mashed potatoes, gravy, apple sauce,and vegetables.
