The answer is:
Rusty Nail
Rusty Nail has a fairly biting and hot taste that is counterbalanced with the honeyed, herbal overtones of the Drambuie. It can be served in an old-fashioned glass on the rocks, neat, or "up" in a stemmed glass. It is most commonly served over ice. A Rusty Nail served without ice is sometimes called a Straight Up Nail.
