Place meat in roasting pan with drip tray. Season as desired with salt, pepper and rosemary. Cook covered in 350° F oven 25 minutes per pound. Meat should reach 165° F when checked with meat thermometer. Uncover meat during last 30 minutes of cooking time. When meat is done, remove from pan and set aside and keep warm. Remove drip tray.
Gradually add butter-flour mixture to the drippings in the pan. Add about 1/2 cup water and scrape any bits of meat from sides and bottom of pan to deglaze. Cook over medium heat, stirring regularly, 5 to 7 minutes or until thickened. Gravy should be medium to thin consistency. Add water to thin if needed.
While roast cooks, make dressing: To bacon and drippings add onions, celery, salt and pepper and sauté until soft.
Put rolls in a large bowl and add bacon mixture. Stir to coat well. Add water, milk or chicken broth to hold mixture together as needed. Mix with your hands. Stuffing should be similar to that of a turkey stuffing. It should squeeze through your fingers when it is the right consistency.
Press into 8-inch square cake pan that is 2 inches deep. Bake in 350° F oven 30 minutes. Remove from oven; immediately add raisins and apples and stir to combine. Bake an additional 15 minutes. If top of dressing becomes too dark, cover pan with foil.
Reheating meat if necessary in microwave, serve meat with dressing that has been topped with gravy.Makes 6 to 8 Source:
