Beef Brisket w/Gravy

Why I Love This Recipe
So I wanted to make a brisket as is tradition on New Year's, but I get tired of the Corned Beef n Cabbage. I dug around on the Interwebz and modified one I found for a Crockpot to use what I had around in the way of seasoning and condiments, and made gravy from the juices! It was YUM!
