Q1630In 1894 two brothers running a Michigan sanitarium left boiled wheat standing for a day. It went stale, and rolling it produced flakes instead of sheets. Breakfast has never recovered.
The Kelloggs were trying to make an easily digestible food for patients. The staleness had let the moisture distribute evenly, so each grain flaked separately under the rollers. Patients loved it. The brothers then fell out badly: Will wanted to add sugar and sell it widely, John thought that betrayed the health mission, and they spent years in court over the family name. Will's company became Kellogg's, and the accidental flake became one of the most eaten manufactured foods on Earth.
