Abstract
Abstract A hot cereal is prepared by treating a cereal grain with a slurry resulting from the treatment of a grain-water mixture with starch-converting enzymes, heating the mixture until the grain is at least partially cooked, flaking the cooked cereal, and, optionally, agglomerating the flakes. It is preferred that the flakes be agglomerated for packaging in single-sized point of sale containers. This cereal has a rich, nutty flavor and when prepared does not have a gummy texture.
