Baked potatoes

[Thacksf]

Maybe I just missed it, but has anyone else cooked potatoes in cast iron on the threshold of the oven? I got a small (7") Dutch oven and dumped in a few potatoes, rubbed in olive oil, with salt and pepper. I threw in a Vidalia onion too. I covered it, then put it barely inside the oven on the threshold, rotating it a couple of times. It was easy and they were perfect! It took about 30-40 minutes for them to cook. The picture is the dutch oven, with a 2" thick NY strip steak in the oven.
