Apple juice, brown sugar, and mustard give this corned beef that delicious sweet-and-salty flavor often found in baked and glazed hams. The slow cooker makes it tender and easy. The addition of carrots, onion, and cabbage makes it a complete meal that only needs rye bread or dinner rolls with butter. A simple dessert of ice cream, cookies, or brownies is the perfect way to top off this dinner. And if you're celebrating st. Paddy's day, irish soda bread would be the ideal finale.
