Food-grade plastic containers for flour storage?
I've decided to keep about 25 pounds of flour - both bread and AP - on hand. I'm tired of running out and buying 5-10 pounds of flour at a time and always running short - not to mention that the larger quantities are less expensive. I do a fair amount of baking so it wouldn't be LONG term storage.
So...doing some research...I've found that food-grade containers are recommended. While I have some air-tight Tupperware/Rubbermaid containers which hold about 5 pounds each, I thought I'd acquire some which hold at least 10. I've also learned that those nice large pet food containers which would be perfect aren't necessarily 'food grade'. Nice, huh? I know King Arthur sells flour storage containers, but with postage, the 4 containers holding 10 pounds each would be about $70US - not very practical.
So, what storage ideas have you come up with?
