In a medium size saucepan, add potatoes with water and let cook only halfway through on low heat
In another saucepan, add milk and bring to a boil. Add ginger, cinnamon, and nutmeg. Add vanilla extract if using. Add sugar and sweetened to taste.
Drain water from potatoes once they are halfway cooked. Add potatoes to milk and let cook for an additional 5 minutes until the potatoes cubes are fully cooked and all flavors have blended. Remove from heat and serve hot.
This recipe is better with boiled milk in my opinion. It also tasted creamier.
