I have some fish that I am wanting to cook in the oven. Now normally I would put some foil down on a cookie sheet and then pop it in the oven. But, I got rid of all my metal cookie sheets since I love cooking with the stones. I have the square, the rectangle and the deep dish, so I have options to use, but am not sure about putting the fish right on the stone. Has anyone cooked fish with a stone with foil?
