Well, I thought, we'll just see about that.
I decided to perform a test and bought specialty flour to pit against my Gold Medal standard. I couldn't find stone-ground white flour, but decided Bob's Red Mill would do the job, as it is both organic and unbromated. Unbromated? I have since learned that this means the flour has not been treated with potassium bromate, a carcinogenic additive illegal in many countries, but not this one. I know. Sorry to darken your day with grim factoid.
In any case, this morning I made two versions of the starter sponge for the Modena Mountain Bread, which I will bake tomorrow.
Three hours in, some interesting results. The bowl of organic sponge has risen measurably higher than the slothful nonorganic. I'd give it a good two inches, plus there are dozens more bubbles. I was sort of rooting for the Gold Medal because I'm cranky, but now I'm just thrilled that there's any difference at all. This counts for high drama in my world.
Hope you're all suitably impressed by how productively I'm using my time during this first day of official unemployment.
