Double Boiler with Cooktop

I love the Lorena with Rocket Cooktop!  This would make canning outside so much easier than just using a single rocket stove.  The cooktop is where I would get my jam (or whatever I'm canning) started while I used the double boiler option at the Lorena to boil my jars.  This is now on my list of "I want..."!



I would probably leave mine (when I build it) out in the open so I'll need to think of a different outside cover besides cob to protect it from the elements.
