To prepare the meat, first trim away any excess fat, gristle, or sinew. Then, cut the meat into small, manageable pieces. Freezing the meat for about 15-20 minutes before grinding makes it easier to handle and produces a finer grind.
Cut the beef into small, manageable pieces.
Place the beef into the bowl of the food processor, making sure not to overcrowd it.
Pulse the beef until it is ground to your desired consistency, using short bursts of power instead of continuous processing.
Check the consistency of the ground beef and pulse it again if necessary.
Remove the ground beef from the food processor bowl, and mix it by hand with your preferred spices and seasonings to add flavor.
Store the ground beef in the refrigerator or freezer until you are ready to use it.
