Bring milk to a full simmer in a small saucepan. Add quinoa, return to a simmer and reduce heat to the lowest setting. Cover, leaving a tiny crack for steam to escape, and simmer until about two-thirds of the milk has been absorbed, about 15 minutes.
Remove from heat and stir in egg white, brown sugar, vanilla and spices. Return pan to stove, covering again with a tiny crack for steam to escape, and continue to cook on low until almost all the milk has been absorbed, about 5 minutes.
If desired, serve with additional milk and garnish with coconut flakes, nuts and/or additional brown sugar.
