Granula is considered to be the first ready-to-eat cereal. It was the creation of Dr. James Caleb Jackson in 1863. He operated the Jackson Sanatorium known as Our House on the Hillside in Dansville, New York. At the sanatorium he treated patients with hydrotherapy ( the water cure), exercise, and healthy foods. The home was run in a smoke-free and alcohol-free environment. Dr. Jackson started the Our Home Granula Company to sell his cereal and his Somo coffee substitute, which was a grain based coffee substitute. The doctor also had his own magazine, "The American Water Cure Journal and Health Reform Magazine". In the magazine the doctor ran the add, "Eat Granula, Drink Sumo". The cereal wasn't really ready-to-eat as it was tough and tasteless and had to be soaked in milk overnight before it could be chewed. The so-called recipe for Granula: Graham flour (wheat flour) water Mix the graham flour with the water. Bake this mixture until it becomes as hard as a brick. Break the brick pieces into smaller pieces and bake them once more. To serve, soak the Granula overnight or until soft enough to chew.
