I hate making ground beef and ending up with giant chunks, and when you do get them broken down they're long and look like little worms. Just a bad sight. My Mom taught me a way to make ground beef that instantly breaks it up. I always thought it was silly and never did it, until those little beef-looking-worms started getting to me.
It's pathetically simple, too !
You have your ground beef in the skillet, right ? Put it in there. Turn your buner on, put hte skillet on it. Good? Now add 1/2 a cup of water. Just plain tap water. Cook your beef like this, and voila.. perfectly crumbled ground beef ! Just have to drain out the water when you're done, of course.
