I canned celery a couple of months ago. I had never heard of doing this until I got Jackie Clay's canning book (you can get it at BackwoodsHome.com). What do you do with canned celery? Well you put in soups and stews and casseroles. And I dont have to worry about celery going bad in my fridge before I can use it all either. I have dehydrated celery too but I think the canned is much better cause you can throw in all that yummy celery liquid in the soup and add some flavor. It will last longer than the dehydrated celery too.
