My friend Gordon was telling me about the time he visited a flour mill. He watched as they prepared the flour for white bread, and what he saw blew his mind (and turned him off white bread forever). They poured bleach into the flour, the same kind of bleach Moon Knight would use to wash his spandex leotards.
At first, I doubted his story. I mean, there’s no way they would actually use chemical bleach to whiten the flour, would they? After doing some research, it turns out it’s true. Chlorine, chloride, oxide of nitrogen, nitrosyl and benzoyl peroxide mixed with a medley of chemical salts are mainstay ingredients in your loaf of Wonderbread.
So that’s what they mean when they call it “enriched” flour.
