Popcorn Beef

Last night Alan tried a new twist on our regular roast and potatoes Sunday dinner. He decided to cook some corned beef like we do a roast in the crock pot. I love Alan. He made the entire dinner and right as it was ready, I had to dash out the door for a violin practice at the church. When I got home, I asked the boys how dinner was and Taylor exclaimed, "We had popcorn beef!" Corn beef...popcorn beef, what's the dif?
