Don't be afraid of all the garlic in this! It gets really mild from the long cooking process and gives the meat a wonderful flavor. This is a favorite for me, and I hope it will be for you, too. Different brands of beer will give you different amounts of sweetness ranging from bitter to malty (common beer characters). Try going with less sugar until you know how your beer will taste (as most of them add some amount of sweetness regardless).
03Add the bouillon cubes to the hot water and stir to dissolve; add that to the skillet along with the beer, brown sugar, mustard, and vinegar; stir to mix well.
04Pour mixture into the bottom of the crock pot.
05Place roast on top of liquid, cutting into pieces if it doesn't lay flat.
06Set the crock pot on low and cook for 7-8 hours.
07Remove meat from crock pot and pour liquid into a pan on the stove; heat to a boil, and mix a slurry out of the cornstarch and water; thicken pan liquid with slurry to make a gravy.
08Serve gravy over meat or with potatoes or noodles.
