I was wondering the same thing. My brother sells cheese and gave me a block of high temp cheese once which I thought was American. I put it on some burgers and really put the heat to them. The cheese did not melt.Where did you get the cheese are you sure it was Hi Temp wonder if they packaged it wrong or something ??? weird
When you stuff with a grinder you dont use a grinder and knife. You use a stuffing star or kidney plate made for stuffing and yes the auger could smash the cheese but you would still have chunks of cheese in the meat. The cheese could have been lacking the Sodium Phosphate and or Powdered Cellulose.All due respect Stuffing does have something to do with it, if your stuffing with a grinder that is too small or wrong plate or leaving knife in etc..
