Milk is a traditional ingredient in various classic cocktails and provides a creamy texture and soft flavor base that blends well with many types of alcohol. It is used in famous cocktails like the White Russian or the Brandy Alexander, where milk's silkiness complements the strong flavors of coffee liqueur or brandy. Additionally, milk can be used in hot alcoholic beverages like Irish coffee or in holiday drinks like eggnog, where it provides a rich, comforting texture and helps balance the strong flavors of spirits and spices.
