what's the best way to store russet potatoes?

4. dark cool spot

I keep them in an unheated room or out on the porch in a cardboard box to keep the light off of them. they will keep for weeks, you should be fine. look at them once in a while and chuck any rotten ones (or catch early, cut off and cook the rest)

fridge if no other spot that works. 5 lbs isn't that much, really. big pot of soup, a few baked, a few more some other way...
