Take the puff pastry out of the freezer and let it thaw according to the package directions, usually about 40 minutes at room temperature. While waiting, mix the superfine sugar and ginger powder together in a shallow plate until well combined with no lumps, then set aside. Preheat your oven to 400°F and line your baking sheets with silicone mats or parchment paper.
When the pastry is thawed but still cool, place it on a lightly floured surface. Roll it out to about ½ centimeter thickness, making it as thin as possible without tearing. Starting from one of the long edges, carefully lift the edge with your fingertips and begin rolling the dough into a tight cylinder, like you're making a Swiss roll. Once completely rolled, gently press the edge to seal it.
Use a sharp knife to cut the log into discs about 1 cm thick. Take one disc at a time and position it with the spiral pattern facing up. Dust your work surface and rolling pin with a little flour to prevent sticking. Roll each disc into a thin oval shape, about 3-4 inches long and 2 inches wide, working gently to avoid tearing.
Brush both sides of each oval with melted coconut oil, then immediately dip both sides into the ginger-sugar mixture to coat them evenly. Place the coated pastries on your prepared baking sheets, leaving about 1 inch between each piece since they'll expand a bit during baking.
Bake in the preheated oven for 10-12 minutes, until the Otap turns a beautiful golden brown and the sugar has caramelized. Watch them carefully after 8 minutes as they can burn quickly due to the high sugar content. When done, remove from the oven and let them rest on the baking sheet for 5 minutes before carefully transferring to a wire rack to cool completely, which takes about 10 more minutes. Enjoy once fully cooled!
