Cut all meat pieces into approximately 1 inch by 1 inch cubes

Mix together in a large bowl and place in the freezer for 1-2 hours - or until the pieces are semi-solid

Assemble your grinder per manufacturer, using the grinding die with the larger holes and place it in the freezer to chill; about 15 minutes

After attaching the grinder and placing a bowl under the 'business end', fill the hopper loosely with meat pieces and turn the mixer on to the recommended setting - for Kitchenaid that is level 4

Working at the pace of your grinder gently press the meat through the hopper, alternating somewhat between lean and fatty pieces as you go, until all of your meat has been used

Cover the bowl of ground meat and place back in the freezer for another hour or two

Clean and reassemble grinder attachment using the fine grinding die; place in freezer again for 15 minutes

Repeat grinding procedure, this time with the coarsely ground meat from earlier
