When living in the city, never buy rice from the corner store if it comes packaged in a cardboard box. There is no liner in the box, and you can’t see inside. The rice just sits in there, snug against the smooth, brown sidewalls, in an imperfect seal. After you pour out a cup into some boiling water and all sorts of brown stuff floats to the top, that’s when you realize that at some point between harvesting, processing, packaging, and sitting on a shelf, your box of rice became infested with bugs. Rice in a plastic bag mitigates this problem. Look in the bag, check for bugs. No bugs? Buy the bag, and store in the freezer.
