slaga, I posted this a bit earlier in the thread:
"I have looked at their web site and video and it shows that you can do steak, fish etc, but you are first suppose to put in their cast iron skillet and heat it up and then take it out and put the meat in and cook. So I think they are getting across that you just can't put a piece of raw meat in and expect it to cook. Would probably also mess up the stone for cooking pizzas.
On the video, the opening looks small and I don't think a regular cast iron skillet would fit. I think you probably have to purchase their cast iron stuff to cook with. I didn't want to incur this additional expense. If whoever gets it decides he/she wants to cook other things maybe they will purchase the cast iron cookware and show us what they cooked."
However, maybe if it is a sous vide and already cooked we could find a somewhat flat griddle that we could slide in to protect the stone from grease, etc. I will look around the kitchen and see if we have something that would work.
