Chullin 114: Exceptions to the Prohibition of Cooking Meat in Milk

Today's daf tells us about the exceptions to cooking meat with milk.  Cooking bones, tendons, horns or hooves in milk does not make a person liable.  Cooking meat in whey is also not a liable action.Steinsaltz teaches us that there are no reasons given as to why certain parts of the animal can beckoned with milk.  There is the possibility that these things are not eaten and thus they do not break cross the prohibition.  Other opinions suggest that items that are cooked to add flavour but are not eaten (for example, hard bones but not soft bones) would be permitted.
