To Cook the Potatoes in the Instant Pot: Preheat the oven to 425° F. In the bowl of your instant pot, combine the potatoes, 2-3 cups water, and a handful salt. Cover and cook on high pressure/manual for 6 minutes. Once done cooking, use the natural or quick release function and release the steam. Drain the potatoes and transfer to a rimmed baking sheet, let cool slightly. Finish as directed above from step 2 on.
