canning

[rbeau30]

What went wrong using a turkey fryer for canning?

Apparently, it made the aluminum of my presto 23 qt canner too maleable, and the bottom became round. The sudden loss in pressure made half of the quarts explode inside, and the rest loose most of the liquid inside.

Didn't get a whole lot for scrap. :-(

BTU output was too high I am guessing. Upon looking at the instructions (for which I promptly discarded when unboxing) it says not to use a fryer burner.

Yes, the aluminum cannot deal with that amount of energy. One way around it is to get a circle of steel similar in diameter to your canner, about 3/16 or 1/4" thick and set that on the burner under the pot. This is how I have run my canner on a big propane camp stove.

I looked on craigslist and picked up a used cook top for $10 (think the burners of a stove without the oven). Planning to install in a cabinet on the back porch. I commonly run at least two canners at a time.

Kind of what I figured. My outdoor burner is 200k BTU, so I'm thinking it would be a bit high.

Item 8 on Page 2 of the owners manual say no higher than 12K BTU.
