We are just learning ourselves but you need a grinder and then you grind them into flour. We bought the hard white this time that is good for breads, rolls, etc. There are other varieties.

Like this, kept in a sealed food storage bucket supposedly they will last 20 years or so. But once you grind them into flour, they are only good for a week or two because the oils released can go rancid.

That’s similar to items that will last a few years in their original containers, but need to be refrigerated or used once they’re opened.

Something to consider when deciding on what size cans or bottles of a particular product you are buying – a large can is great if you are going to use the contents within a short time or have some refrigeration.

Smaller cans may be comparatively more expensive, but easily used up before they spoil.
