Canning your own roast beef lets you store dozens of mini homemade meals in the same time it takes to preserve fruit. Canning cooked roast beef reduces the chance of spoiling and saves you from cooking and seasoning the meat after you eventually open the jar. But don’t assume that the canner you used to preserve last month’s apricot jam is safe for canning roast beef. According to the National Center for Food Preservation, only a pressure canner can safely preserve low-acid foods such as roast beef.
