Fry 5 pounds of ground meat. When meat is cooked transfer it to a colander and rinse the meat under hot water to remove fat. Place washed meat back into cleaned skillet. Fry meat again over med/low heat stirring often until you see no more steam. Keep flame low once the rocks are browning up nicely.
Place twice cooked rocks into an oven-roasting pan. Turn the oven to 200 degrees F, stirring and turning occasionally as meat continues to dry. One to two hours should be enough. Remove the meat from the oven and check for dryness. Store in Jar or Ziploc bag.
If you want to can the hamburger rocks for long-term storage, preheat some canning jars in the oven at 250 simmer lids as usual. Put the rocks into the jars while hot, and then seal jars. After 15 minutes or so the jars will cool and you will hear the jar lids "pop" as they seal in place.
