The Rusty Nail cocktail is a classic drink that combines two main ingredients: Scotch whisky and Drambuie, a sweet, herbal liqueur. Typically served over ice in an old-fashioned glass, it offers a smooth and rich flavor profile, making it a favorite among whisky enthusiasts. To prepare a Rusty Nail, mix one part Drambuie with two parts Scotch and stir gently. Some variations may include a twist of lemon peel for added aroma. This cocktail is known for its simplicity and is often enjoyed as a nightcap or during social gatherings.
