The other issue that comes to mind that you might have to watch if you can red beans with sausage, is the fat from the sausage. It is my understanding that you can't can very much fat because it tends to cause spoilage faster than other ingredients. If you were to skim as much as possible off before you packed the jars, you'd be in good shape.
It is obvious I have a lot to learn about pressure canning. I don’t have a caner yet will be looking for one in the next week or so.
