Please forgive me for just jumping in, because I know you were asking PapaBear3625 about wheat...but you do NOT have to grind wheatberries into flour before using them. You can BOIL them!...whole...and it’s a lot “like” rice...not quite of course. But we eat it on occasion that way here...either put salt on it, or butter. I get tired of it like that QUICKLY though.
In Greece, Eastern Europe and Lebanon, they make a dish called Koliva with boiled wheat mixed with honey, sugar, and fruit.
While I think of it, honey is another thing that keeps a long time, and is valuable for improving the taste of otherwise-bland foods. Honey can also be used as a topical antibiotic for skin wounds.
