Ejg, Armyof1 has the right idea! and there are lots of sites that talk about this. The danger is bacteria forming while you are working with the meat. If I were doing it the meat would still have that icey look but thawed enough to run through grinder. Also Use a double bowl, Fill a bowl with ice cubes, place place second bowl on top ice! As you grind put that meat in the bowl with ice under it keeping it very cool! wrap and refreeze ASAP! Good Luck and lets us KNow!
