Which cocktail combines Scotch whisky with Drambuie liqueur?

The Rusty Nail is the cocktail that combines Scotch whisky with Drambuie liqueur.

Drambuie is a sweet liqueur made from Scotch whisky, honey, herbs, and spices. Combining it with Scotch creates a drink that is richer and sweeter than a simple whisky pour. The cocktail is commonly served over ice and may be garnished with a lemon twist, although recipes and proportions vary.

The Rusty Nail became particularly associated with mid-20th-century cocktail culture in the United States. Its exact origin story is disputed, and several earlier drinks used similar combinations of whisky and liqueur. The name became firmly established for the Scotch-and-Drambuie mixture.

It is easy to confuse the Rusty Nail with the Rob Roy, which combines Scotch with sweet vermouth. The Godfather also uses Scotch, but its second ingredient is amaretto rather than Drambuie. These differences are small in appearance but define separate cocktails.
