I season my "alaska" (spring) handles, the same way I season the paddles. I do remove them though, and set them by themselves in the same oven. I think it takes more heat than most ovens can produce, to take the temper out of them. I've not noticed any difference with them at all.
Chuck, what you say here about ovens not producing enough temperature to take the temper out of handles, I SUSPECT, but don't know for sure, that the same can be said for bale handles, like on dutch ovens and griddles.
I know Steve Stephens always said they would take the temper out, but it seems to me that this is not true because the metal went through a lot hotter process than a stove oven can produce, so it seemed to me that the stove would not hurt the bail handles, but I don't know for sure. Thats just my thinkin.
Does anybody know for sure if this will take the temper out of the bail handles? By that, I mean, did it ever happen to you? :-/
