Make incisions in the pork every 2 to 3 inches, and insert garlic slices. In a small bowl, combine salt, pepper, sugar, and marjoram, and coat the pork evenly with the mixture. Cover with plastic wrap, and let stand at room temperature for 1 hour.
Preheat oven to 375 degrees. Sprinkle flour over the pork to lightly coat. Shake to remove any excess flour. In a large skillet, heat oil over medium-high heat. Add pork, and brown on all sides. Transfer pork to a large roasting pan. Grate onions over the pork. Add 1 1/2 cups water to roasting pan, and roast, covered, for 1 hour, basting occasionally.
In a medium bowl, soak prunes in enough cold water to cover, for 15 minutes. Drain, and add to roasting pan. If necessary, add a little water to roasting pan to prevent pork loin from sticking. Cover, reduce heat to 325 degrees, and roast until temperature of pork loin reaches 140 degrees on an instant-read thermometer, 15 to 30 minutes.
Remove pork loin from roasting pan, and let rest for 10 minutes. Place roasting pan on stove, heat over medium-high heat, and cook pan juices until reduced and thickened enough to coat the back of a wooden spoon.
Slice pork, arrange on a serving platter, and serve with sauce.
I have always thought a pork loin was difficult to make, but I am defintely going to give this a try! Thank You Mrs. Kostyra!
I've made this recipe several times, and it is absolutely delicious. It's comfort food to me. My grandmother made recipes like Martha's mother did. Thanks so much! The red cabbage is a must with this wonderful pork recipe.
