Steam or a Hot Surface

Toast

Due to my setup I cannot have both steam or a hot surface. Either I use the drip tray as a steam tray but the dough rests on the rack with foil as a base or I can preheat the drip tray and then transfer the dough onto that. But I can't do both. The second way sacrifices the steam. 

Which way is better? 

I don't know, but I think steam.  There have been numerous posters that have tried cold DO to hot DO and found no difference.  There are even recipes where the dough is loaded in a cold oven,  That suggests if you can only have one, steam is the one. 

Get your stone up to 500F with lava rocks in a metal pan on the bottom rack of the oven,  When the bread gores in, toss 2 C of boiling water onto the stone and shut the door.  Turn the oven down to 450 F for steaming. 

Hot surface + cover.  Not sure if your setup will permit this option but, if it does, you get the best of both worlds.  It could look like a DO, or a stone with a bowl/cloche/other to cover the loaf for the first 15 minutes.  Heat from the surface to drive oven-spring and the cover to hold the steam from the bread itself.
