Hmmm... For some reason I can't edit the above message, but I just want to add -- if you are filling bag after bag, you want to re-heat it to about 280, and then do the 280 -> 230 with the fan on. With each iteration, the bowl and material tend to heat up, so you'll need to reheat it a bit lower than 300, or you'll get that popcorny taste that tells you you're over-cookin' it.
