Deciding whether to fork out for a lidded oval le creuset (on offer on Amazon right now!), or go with a 1970s chicken brick (which I've never used) or stick with my open, low-ish sided roasting pan- should I get one with a rack in the bottom? I like a 'browned' chicken- do you achieve this by de-lidding the lidded options, but does this defeat the 'clean oven' advantage? All thoughts gratefully received.
