Another very simple and cheap staple is white rice. I store it in 1/2 gallon Ball glass canning jars with a desiccant and an oxygen absorber. Store the jars away from light. It will keep for 20 years at least that way. I date the jars and we opened one this week from 2011 and the rice is perfect. I buy jasmine rice from Thailand in 25 pound bags at the Asian store. Remember a very large portion of the world’s population basically lives on rice.
FYI, because brown rice is fatty it will go rancid in a few months. For longer term storage I put it in the same jars and store in our upright freezer. So far it has lasted as long as needed.
Yep. Have lots of rice and beans.
