Step 1: Preheat oven to 325 desgrees F. Grease a very large roasting pan.
Step 2: Season lamb generously with salt and pepper. Place into the roasting pan along with carrot chunks.
Step 3: Heat oil in a large skillet (use as much oil as needed). Add in onions; saute until softened. Add garlic; saute 2 minutes. Add to the roasting pan along with bay leaves and rosemary. Pour in the red wine and broth. Cover tightly with heavy-duty foil and cook 3 hours, basting occasionally with the pan juices (a turkey baster works well for this).
Step 4: After 3 hours of cooking, remove foil and roast 30 minutes. After 30 minutes add in the plum halves and cook 20-25 minutes, until the lamb is fall-off-the-bone tender and the liquid has slightly reduced.
Step 5: Remove the lamb roast, vegetables and plums from the roasting pan; set aside to keep warm. Remove all bay leaves and discard.
Step 6: Place the roasting pan on top of the stove over medium-high heat. In a small bowl combine the soft butter and flour until it forms a smooth thick paste, then whick into the sauce. Simmer 8-10 minutes whisking frequently. Stir in red currant jelly, then season with salt and pepper to taste.
Step 7: Return the lamb, vegetables and plums to the pan. Serve warm.
