Somehow, I actually managed to undercook the corned beef brisket. I could have sworn that I left it in long enough, but it was still a bit on the tough side. The veg and taters came out great, however, and I've lots of braising liquid to strain and save for the next time. (Many people don't know that braising liquid can be re-used, and packs more flavor with each successive usage.)
But der Brucer was happy.
