I've suspected it for some time, and I guess I was in denial. I finally looked it up online and discovered that my beloved Premium Saltines crackers have indeed been changed, and in a bad way.
It isn't just the lack of salt, not just the texture, but the old buttery flavor is gone. Turns out they quietly changed the recipe some time ago. Online complaints are everywhere. So sad.
I know, I know. I have no life.
