Line a baking sheet with parchment paper and preheat the oven to 400
Bring a medium saucepan of water to a bubbling simmer over medium heat
Add the potato chunks to the water until slightly softened, about 8-10 minutes
Meanwhile, mix the dry seasonings together in a small bowl
Strain the potatoes and lay them out on a wire rack until the outsides have dried. This is so they will crisp up nicely in the oven
Meanwhile, melt the coconut butter and coconut oil together over low heat, until liquid
Once the potatoes have dried, transfer them to the parchment lined sheet and press down with a large spoon until the edges have ridges
Using a pastry brush, spread a thin layer of the coconut mixture on each potato
Sprinkle some of the spice mixture over each slice, and rub it in a bit with your finger
Gently turn oven each potato, and repeat
Pop into the oven for about 15 minutes, until the bottoms are crispy, then gently flip them over and roast for another 10-15 minutes until they have browned
