Amaranth Breakfast Porridge with Cinnamon and Sugar

Bring the milk and water to a boil in a medium saucepan. Whisk in the amaranth, reduce the heat to low and cover. Simmer for 30 minutes, stirring occasionally, until the liquid is absorbed and the amaranth is tender. Remove the amaranth from the heat and stir in the butter, brown sugar and cinnamon. Serve warm.
