This is a straightforward whiskey cocktail that checks every practical box for a Charlotte weeknight. Irish whiskey, lemonade, ice, and lemon are all stocked at every major chain—Harris Teeter, Food Lion, Publix, Walmart, ALDI, Kroger—with no special stops required, and the cost per drink lands under $3 even with decent whiskey. The five-minute claim is honest; you're literally pouring and stirring. The only caveat is that it's a single serving, so scaling for a group means you'll be bartending all evening rather than sitting down with guests.
