A flour made using an admixture composed of starch-containing grain, seed or fruit of a cereal grain or grain legume of low water content extruded in a single screw extruder at an ultra-high extrusion pressure producing an extruded functionally enhanced flour usable as an instantized flour by only adding water. When water is added, the flour forms a paste or dough that is three dimensionally formed or shaped into food products that can be cooked or baked in an oven into human or animal edible food products. The extruded functionally enhanced instantized flour also can be used as an ingredient in other edible food products. A preferred extruded functionally enhanced instant flour is extruded at ultra-high pressure from an admixture composed substantially completely of one or more cereal grains and/or legumes using only the moisture present in the cereal grains and/or legumes.
