In 1898, two brothers were working in a sanitarium in Michigan. They were trying to find healthy food to serve to their patients and when they accidentally let some boiled wheat go stale, they decided to see what they could do with the product. When they tried rolling the hardened dough it cracked into flakes, which the brothers then toasted. Their patients liked it, so the brothers started experimenting with other grains and corn.
What is cereal (specifically corn flakes)? (Side note: these are the Kellogg brothers)
