I was totally nervous too - this was the most fussy cake pan I'd ever used. But one simple thing did the trick: Baker's Joy. This nonstick spray has flour added to it to give an extra-clean, smooth release. Usually I just grease and flour my pans myself, but all the edges and crevices on this one would have made it really hard to do it evenly, without goopy lumps, and I'm sure I would have missed a spot. Baker's Joy goes beyond regular nonstick sprays with that flour coating, and it really works amazingly well.
Also, I make sure that I let the cake rest for exactly ten minutes before trying to remove it; Nordicware insists on this in their instructions. Ten minutes - no more, no less.
Anyone else have some good pan release tips?
