A caramel macchiato is an extremely popular espresso-based coffee beverage that originated in Italy. It consists of a shot or two of espresso, steamed milk, and a drizzle of caramel sauce. The espresso is poured over the steamed milk, creating a layered effect. The sweetness of the caramel sauce complements the bitterness of the espresso, resulting in a rich and creamy coffee drink with a sweet and slightly nutty flavour. It is enjoyed as a morning or afternoon pick-me-up by millions of people.
