Perhaps the ideal slow cooker piece of meat. Beef shanks transform from a tough lean cut into an unctuous, delectable dish given enough time simmering in broth or even just water. We slow cook for 4+ hours then pull the meat from the pot, shred with forks, and add carmelized onions and/or tomato sauce. While shredding the meat and carmelizing the onions reduce the leftover beef juices in the stove top and pour them over the final product. A simple, out-of-this-world meal results.
