They called for 4 and a half hours at 325F, so I thought this would be a good test, and it was nice and sunny out.
Since I had never used this oven, I knew I was taking some risk, but who cares right ? Adding to the recklessness, I decided to use a 1 lb disposable propane cylinder, the ones I despise.
The results while not perfect, were actually pretty good. It turned out that only one of the two were necessary, but leftover turkey is never a bad idea, salmonella notwithstanding :)
On the technical side, the oven is well insulated and very miserly on fuel. 4.5 hours and it consumed about 11oz of propane, or almost 3/4 of a one pound tank; that's not too bad.
All in all, it was a Happy Thanksgiving...
