Orange liqueur—likely Cointreau or Grand Marnier—is the only ingredient that demands a liquor-store trip; most Charlotte grocers don't stock it. The five-minute claim holds up if you brew coffee ahead or use instant, though pulling fresh espresso adds real time. At roughly $8–12 per drink when you factor in the liqueur and quality coffee, it's an occasional treat rather than budget weeknight fare. This is a single-serve dessert drink that doesn't keep, best savored fresh and meant for one person, not a family meal.
