This is a solid weeknight side that plays directly to North Carolina strengths—sweet potatoes are a state staple, cheap year-round, and the Instant Pot cuts real cooking time to under 15 minutes once the pot pressurizes. All ingredients are basic grocery-store stock at Harris Teeter, Food Lion, Walmart, or Kroger; coconut milk and cayenne are standard pantry items with no special stop required. The stated 25 minutes is honest if you count pressure release, and six servings at roughly $1.25 per serving (driven by the sweet potatoes themselves) makes this a bargain. The only friction is that this reheats unevenly—the mash can dry or separate in the microwave—so it is best eaten the same night, and it demands a second of attention when you add the lime juice and cilantro at the end rather than cooking through the whole time.
