What was the first cold breakfast cereal invented in 1863?

Breakfast cereal (or cold cereal or cereal) is a typical breakfast made from refined cereal grains. Traditionally, it is served as breakfast mainly in western cultures. Cold cereals, such as porridge and grits, have the longest history. Ready-to-eat cold cereals, which appear at the end of the 19th century, are most commonly combined with milk (traditionally cow's milk), but can also be served with yogurt instead of or eaten plain. Fruit or nuts can be added. Many breakfast cereals are processed by extrusion. Some firms are marketing their products for the health benefits of consuming oat-based and high-fiber cereals.

Granula was the first cereal breakfast to be made. It was invented in 1863 by James Caleb Jackson. Granula may be represented as a larger and tougher version of a very similar later Grape-Nuts cereal. Granula, however, consisted predominantly of bran-rich graham flour provided in the form of nuggets. Cereals had to be boiled overnight before they could be consumed.

The cereal was made from Graham flour dough rolled into sheets and fried. The dried sheets were then broken into pieces, baked again, and broken into small pieces.
