If it's too dry for your taste, put a moist piece of paper towel in there.
I'd store that in jars or the freezer.
Can I just burp the bag once a day?
if it’s semi old it’s prolly already been “burped“ meaning if not 100% sealed is getting a way to de-gas. if fresh and never burp . Open the bag once a day for 30min-1hr for 7 days.
