1. In a jar.
The grains or beans I plan to use before the others I bought in bulk I keep in jars.
2.In Tupperware containers
The cooked beans and grains I keep in a Tupperware container.
3. The grains and (some) beans (that have the same shaped -or similar-packaging) I keep in a Bob's Red Mill box. You don't have to eat that brand, but I love them! If you don't just get a similar box, or buy and give to a food shelter and keep the box.
