Wow, I just got an idea.
Yestarday, I put too much olive oil on my pizza, and it got on the bottom crust.
So I threw the soggy bottoms back on the steel for a few secs and eureka!
They came out stiff and crispy.
I saw how people usually reheat a slice of pizza with oil in pan, but now I'm gonna put the whole pizza on the steel with it being oiled on the bottom with shortening.
But i'm afraid it will catch on fire.
