Uneven Cooking Propane Oven
Just moved into a new house with a propane range/oven.
I seem to be having a strange problem in that whenever I cook any kind of substantial meat/roast it takes twice as long as it should.
(20 lb Thanksgiving turkey took 6 hours!)
No problems, though, cooking/baking any other foods. All my Christmas cookies came out fine...spot on as far as timing...if the recipe called for 10 minute baking time, they were baked perfectly in 10 minutes.
Same thing with other foods: casseroles, potatoes, etc. Everything except meats cook fine!
Yesterday I tried to cook a pork roast that should have taken 2 hours. After 1.5 hours the internal temperature of the roast was only about 120! I've tested with an oven thermometer and the temperature is accurate...even after an hour.
Is propane the problem? Although I am not at all new to cooking, I've never cooked with propane before. Isn't heat...heat? No matter the source?
Thanks in advance for any input.
I've never heard of any differences between propane and other fuels. Stoves, ovens, fryalators (and clothes dryers) must be fitted with an adaptor "kit" when using propane instead of natural gas. One would imagine that makes up for any differences.
You noted that you tested with an oven thermometer. I wonder what the on/off cycle time for your oven is. If short-baking things are coming out alright I'd imagine that the opening of the oven door triggers the fire, keeping temperature even. Perhaps it takes a long time for the oven to re-cycle after it's been on for a while; resulting in a diminished temperature, for a moment.
Just a thought.
