Corned Beef and Cabbage Pork Roulade with Bittersweet Guinness Gravy

Happy St. Patrick's Day! And for most americans, just an excuse to drink a lot.
A few years back i worked the irish bar alley on third avenue, being my place one of the biggest, but not irish at all, we would get all the overflow from the irish bars. Let's just say I'm glad i no longer work there!
But will celebrate this paddy's day sitting on my porch drinking a cold guinness and eating a good meal. How i love being a grownup!!!
