A SEARCH will bring up many threads about outdoor canning and the subject has been covered in great length. See the link below for a bunch of threads.

Here is a link that might be useful: Outdoor canning- propane

personally, i hated it. the inability to wash my hands or rinse something was a pain. and I only had to walk inside to get running water. Also, I had a huge problem keeping the turkey fryer burning consistently. More of a problem with pressure canning, but using a bwb won't be as bad. Wind was culprit. I'd definitely recommend some sort of shield around the burner in any case.

You are a much braver person than me. this sounds like a big project and with an audience to boot.

tietie, thanks! It looks like the wind is expected to be 7mph on Sunday when I'm canning.

Yes, I'm a little nervous. When they first asked me to do it, we thought we'd have electricity. I'm keeping my fingers crossed!

You can solve the water problem with one of those large water cooler/containers. The kind the construction workers use. Fill it with hot water.

Wind shields are easy to construct and almost mandatory - the thread here on propane cooking outside has photos of mine in it. The heat sources will be a problem possibly - many turkey fryers don't get hot enough and heat control on them can be difficult.

Too late now I know but there are much simpler recipes with less complex staging to use for demos. When we do them we stick with recipes that only have 2 stages max and work with smaller batches.

I do wish you good luck. Be prepared for many, many basic questions. :)

Dave, thanks! Great idea on bringing hot water in a large thermos!

Not too late for appropriate recipes -- I'm supposed to do three more canning demos this summer! I'd love suggestions. I do want to do one pressure canning demo if possible, was thinking of doing spaghetti sauce for that. I chose this recipe because it's fairly reliable, produces an excellent product that most people like, and seems like a pretty safe choice for beginning canners. I don't mind the switchouts -- I've got three hours I can use, so time isn't really an issue.

Dave, is this the thread you're talking about, with photos? It looks like they've been deleted?
