There is a moment every morning, somewhere around four fifteen, when the first tray comes out and somebody has to decide whether the day starts or waits. It is not a machine that decides.
One loaf, cut by hand
The head baker on shift cuts the first loaf of every batch, looks at the grain and presses the crumb with a thumb. If the cell structure is tight on one side, the prove ran cold. If the crust is thick, the deck ran hot. Both are fixable in ten minutes. Neither is fixable after the vans leave.
Why not automate the check?
We have automated plenty. Mixing, proving temperature, slicing, sealing and coding all run on instruments. What we have not been able to replace is a person who has read ten thousand crumbs deciding whether this one is good enough to carry our name on it.
Anyone can bake bread at four in the morning. Staying honest about the batch you would rather not throw away is the harder habit.
Most days the tray passes and nobody remembers it. On the days it does not, the batch waits and a few shelves open an hour late. We have made peace with that trade.
