Irish Corned Beef and Cabbage

A traditional St Patrick's Day dish I make every year.  
But first, what is Corned Beef?
Corned beef is made from a beef brisket that is cured or pickled in brine. Brine is just salt water.
In North America, corned beef dishes are associated with traditional Irish cuisine. However, there is considerable debate about the association of the corned beef and cabbage dish with Ireland.
