Spices and mixed dried fruit make a great flavor for this roast--it's a family favorite. (Don't confuse the dried fruit bits you buy for baking--look for packages of regular size dried apples, peaches, pears and plums).
Trim fat from meat and if need be, cut the meat to fit the cooker (3 1/2 to 4-quart cooker).
Brown meat on top of stove in a Dutch oven. Brown on all side using the 1 tablespoon of cooking oil. Sprinkle meat with salt and pepper.
Cut up any large pieces of dried fruit; place the fruit in the slow cooker; add the onion wedges. Place the meat on top of the fruit and onion; sprinkle with allspice and pour in the apple juice.
Cover and cook on low for 8 to 10 hours or on high for 4 to 5 hour.
