Just came across your post...I used to buy it at the grocery store and have them grind it as hamburger is ground. I would then mix it with regular ground beef and make hamburgers, or any dish ground beef was used. It was good and would make the regular i.e. cheapest ground beef much leaner and it was cheaper than the ground beef (Back then about 25 years ago. Not sure if it is still cheaper. If you have a food processor or a meat grinder you could grind it yourself.
