Home canning soup
Is it safe to home can vegetable barlery soup? Or beef barley soup
St. Clair County Michigan
The answer is "partially", in other words you can "Can" soup using meat/vegetable ingredients. The barley can't be added prior to canning, but can be added during preparation, when getting ready to eat.
