Every ingredient is stocked at Harris Teeter, Food Lion, Walmart, or ALDI without special shopping, and the total cost per serving runs about $3–3.50 depending on whiskey choice—reasonable for a weeknight indulgence. The stated 5 minutes is honest; cold brew just needs pouring, and whipping cream takes seconds with a whisk. It's a single-serve treat, not a family meal, and it does not reheat, so this is strictly a same-night drink. The main catch is that demerara syrup is not universally stocked—you may need to make it yourself by stirring demerara sugar into water—but that adds only 2 minutes and costs pennies, so it's a minor friction, not a dealbreaker.
