another oven question
I responded to a recent question about dealing with a small oven, and it got me thinking...
Is there any reason not to bake on two layers? I have two racks in my oven, and enough tiles to cover them both. Could I use both racks at once? My electric oven seems to heat from the bottom, so I don't think there's any risk in burning the tops of the upper layer.
Is this a bad idea, or is it fairly safe?
