We grind our own meat in the kitchen. In this way, we have total control over the freshness, quality and the kinds of cuts that go into the mix.
Taste. Some packages of ground meat can contain meat from dozens of animals, all processed together. If you grind your meat, you have total control over the quality and cuts of the meat that you are consuming.
Health. When meat is ground and exposed to air, it can pick up bacteria in the air of wherever it was processed. Therefore, when you buy pre-ground meat, you run the risk of its being contaminated with such unpleasantries as E. Coli and salmonella. By grinding your own, you avoid this risk, plus you can be sure your meat is free of any unquestionable additives or chemicals.
