Did a few more items tonight.
There were two schools of thought that crossed my mind as far as improving my results. First, was warm it up for a good long time to saturate the stone with heat. That way even though it was screaming hot, it may cook evenly. Second thought is catch it on the way up. Tonight, I went with the first option.
I preheated for close to 45 minutes. It was maxing out my temp gun, so I figured I would try the steak first. I tried to elevate it on the pan with skewers. Strip steak, just salt.
Cooked for 2 minutes. Flipped. Tried to keep it on the skewers, but they kept falling because the opening is pretty much the exact size of my pan. So I flipped directly onto the pan.
2 minutes, checked temp. Flipped, 1 minute. flipped, 1 minute more. Final temp about 125.
Actually turned out pretty well, and by far the best thing I've made on the uuni.
I'll post the rest in different replies.
