Steam canner questions

Asked August 3, 2019, 11:02 PM EDT

Hello, I follow you guys on fb and am hoping you might be able to clarify a couple of things with the multi-use steam canner, specifically for using the steam function. I know the recipes must be high acid, follow approved times, etc. 1) the box says it fits 8 pints but I can easily get 10-11 on the included rack, can I do that or do I have to stick to only 8 jars? 2) there is enough headroom to triple stack 4 oz jars or double stack 8 oz ones, would that be allowed? Thank you so much!

Thank you for your question. No experts in this are available over the weekend. Please contact your own Extension office: http://sfyl.ifas.ufl.edu/sarasota/ Good luck!

It's no emergency. Perhaps someone could answer it during the week? The only qualified extension agent in a one hour radius retired a few years ago. There is nobody local to answer :) It's also a question I see constantly on fb groups, so it would be great to know the official answer.

I’ll send it on to one of our state experts.

Hi:

Follow the manufacturer's instructions for operating and loading the equipment. It might fit more jars but that space is for appropriate steam/air circulation to distribute temperature evenly over the containers and meet the thermal processing needed to make the product shelf stable. Overfilling it will cause a process deviation as the temperature will not circulate uniformly over the containers for the time required making them be under processed and allowing bacteria (particularly Clostridium botulinum - Botulism) survive = very dangerous. Stick to loading no more than eight pints at a time as per the manufacturer's instructions. Perhaps contacting the manufacturer directly can give more information. See if they have a mailing address/email or phone number.

Hope this helps. Thank you for using eXtension.
