I was wondering.... I can ALOT ... and last season I had so much to can it was overwelming, all the washing pans, heating the house up, stuff everwhere. If I could can about 45 jars at once it would make it much easier...I can only can so much on one stove at one time. So here's the question on using the galvanized tub comes in, it would be awsome if I could build a fire ander it and can till my hearts content. I would appreciate any help on this subject and what works best for you?
