A homemade honey barbecue sauce adds a sassy flavor to this boneless ham and potato recipe that cooks in the slow cooker.
In a small saucepan, stir together ketchup, vinegar, sugar, Worcestershire, 1 teaspoon oil and mustard. Bring to a simmer and cook for 5 minutes.
Score surface of ham, making diamond shapes 1/2-inch deep. Place ham in a 4- to 5-quart slow cooker and brush generously with the barbecue sauce.
