Soak the groats in a bowl of water overnight in the refrigerator. The groats should be covered at least 2 inches.

In the morning, drain the groats and rinse well (at least 1 minute) in a strainer to remove the gelatinous coating.

In a blending cup for food processor, add the milk, spices, maca, and groats. Blend until very smooth. I used an immersion blender, which was very fast and easy clean-up, but any smoothie-making device will work.

Spoon half of the mixture into a bowl. Top with additional milk to create the desired consistency (this ratio makes a thick porridge), and any additional add-ins you desire.
