This is dead simple and honest about its time—five minutes is accurate, and every ingredient (sugar cube, whiskey, bitters, cream) is available at any Harris Teeter, Food Lion, or Walmart in Charlotte without a special trip. Cost per serving runs about $3–$4 depending on whiskey quality, which is reasonable for a special-occasion drink. The only meaningful drawback is that it's a single serve meant to be consumed immediately, so it doesn't reheat or store, and it requires fresh whipped cream or you're making it with Cool Whip instead. For a weeknight digestif or weekend indulgence, it delivers.
