I actually don’t anything about gluten but she did say something about the brand being insurance against it.
I guess it is processed in a very specific way and in a protected environment.
There’s a source of flour and other grains in a nearby city and they do sell gluten free items, but cannot sell something as gluten free that they have to repackage because of the risk of cross contamination since they are not a certified gluten free dealer.
So, apparently they exist.
For anyone interested in gluten free, there’s a thickening agent that can be used in place of flour or cornstarch for gravies and such called arrowroot. We use it for gravy, not because it’s gluten free but because it makes killer gravy.
