I actually did let it air out overnight before using it but only because it was brought up just before bed. I wonder if it would have made any difference to have used it immediately? I kinda doubt it but I don't know. Maybe I'll try that with the next bag I open... whenever that may be.Thanks for the thread!
Did you "air out" your flour over night before use, or use it rite after you opened the mylar?
It was also stored in a basement that is always cool (no heat down there) with very little humidity.
