I've been reading the threads on no-knead bread here and I'm eager to try it. My only hesitation: I did a google search and found a few people complaining that pre-heating their empty Le Creuset pots in the oven caused discoloration. It looks like many people use Le Creuset for this recipe, though, so I would think it would be mentioned more often if this were common. (If it was discussed here, my search of old threads didn't turn it up.) Still, I love my 5.5 qt pot and am afraid of ruining it. The problems with pre-heating were discussed in comment threads of blog posts that are months old and that the commenters probably aren't checking in on, making it hard to follow up...so, chowhounds who have pre-heated your empty Le Creuset pots in the oven, can you please reassure me that it's ok to do this?
P.S. I do know about the problem with the plastic knobs. I have a stainless steel knob, so that should be fine.
