This is my 1st attempt at Overnight Ciabatta:
Ciabatta Ready for Baking
I used a large half sheet non stick jelly roll pan as the baking vessel. I placed a silicone Silpat mat that fits the pan in the pan. My Ciabattas were rising in a cloche. When they had risen I used a dusted board to transfer them carefully to the Silpat mat. I chose this manner of baking because I have a small oven and I wanted to bake all 3 Ciabattas at the same time on the same rack in the oven. I placed a baking stone in the oven and heated it to 500ºF along with a tray of water in bottom of the oven. I added more water when I placed Ciabatta in the oven. I removed the water tray after 8 minutes. I rotated the bread halfway through baking process since the back of the oven is the hottest zone and I wanted more even baking.
