My main question is, can I use pre-packaged stock (like the stock that comes in those aseptic packs...I get mine at Costco) to use in the soup? Reading the recipe in the Ball Book, I'm kind of getting the impression that they are calling for the homemade stock.
Also, in canning your own soups, can you use rehydrated dried veggies? I have a TON of celery that I dehydrated, and I'm looking for a way to rotate through some of it....canning homemade soup would be a great use!
Thanks!
