Have a very large box of Minute Rice, don't know what to do with it.
Are you channeling your best self with this comment? (If you're not sure, check out our Code of Conduct.)
Since Minute Rice is a dehydrated product, it doesn't need to be further preserved and wouldn't require freezing. The company says it should be stored dry and is good for up to two years after the best by date. Your main concern would be to keep it out of reach of pests, like pantry moths. If you put the box or portion out amounts in to either ziplock or vacuum sealing bags, and it's kept dry and at room temperature, you should be able to keep it and eat it safely for many years. Personally I would use it as bird or squirrel food, as I don't care for the stuff myself.
