Gruel, a mixture of seeds and nuts, used primarily as an addendum to breakfast. Ingredients are sunflower seeds, almonds, and wheat grains. The ingredients are blended in water, placed in a double boiler to inhibit burning, cooked for about 1.5 hours, placed in liter jars and stored in the refrigerator or freezer. Obviously these ingredients have gluten, which some people must avoid.Various grains and nuts could be substituted.
