Daily Life and Compromising

I recall back when I was in denial of having celiacs years ago. I was at my grandmas and she had a old container of flour. I tried a bit of it on a whim, had a earthly flavor tad deep and off and I assumed it was old flour from god knows when. But I did not have a reaction to it, this made me think perhaps it was not gluten but the other crap they put in flours now day. But I kept having gluten reactions and eventually gave up and took about a year before I learned what that stuff was. I was later experimenting with different gluten-free flours and came across sorghum flour....it tasted exactly like the stuff my grandma had in that container. I still to this day do not know why she had that flour....I assumed either some old health fad, or she got it for a porridge.
