i thought maybe i was missing something. LOL!! don’t worry—most of us have over-worried something at one time or another. the only thing i know of that gets ruined (if you can call it that) in the fridge is homemade bread—-but only because it goes stale faster in the fridge.
when i used to buy big bags of flour i would put them in the freezer for a few weeks to kill of bugs—–i’m not sure how my gluten free flour will be affected by bugs—probably ought to freeze it, too.
