I gained a bit of appreciation for the complexity of this dialing-in process when I was in high school...I was staying in a hotel mostly occupied by my extended family for a wedding, and across the street there was a brand new Krispy Kreme store about to open. During the fine tuning stage of the newly installed machinery they were giving away unlimited free donuts, so my cousins and I formed somewhat of a bucket brigade funneling them across the street whilst piping hot. I ate enough donuts over the course of the weekend that I was able to observe the batches getting more consistent...less variation in color/texture/glaze. I thought it must be interesting to be the person traveling to each new location and making the call as to when everything was exactly perfect.
