Do NOT can unless you know what you are doing. You can get worse than bad food. You can get dead. Used to happen fairly regularly. Entire family done in by botulism. I am a historian who specializes in late nineteenth and early twentieth and this really happened. Obituaries for the whole family, dead from bad canning. Nasty. Freezing, for the average person who doesn't want to mess with pressure canning, is easier and safer.
