First let’s address a common misconception. Extra lean ground beef is not always the best thing to use. It’s dry, tasteless, except for that weird liver aroma (think about that for a minute) and soul killing. So, when we go to make the burgers we want to start with medium ground beef–don’t freak out, the extra fat is going to render out of the meat when grilled. For extra flavour and juiciness, combine half-minced pork with your beef. Tasty!
