Place the chopped potatoes in a large pot and pour enough water over them to cover potatoes by 1". 

Season with a large pinch of salt. Bring water to a boil over high heat, then reduce heat to medium high and cook until potatoes are for tender, about 10 minutes.

Remove potatoes from the pot with a slotted spoon and place them in a large bowl.  Add coconut milk, chicken broth, ghee, garlic powder and salt and either mash with a potato masher for chunkier mashed potatoes, or use an immersion blender or food processor to blend until smooth.
