Half and Half is a dairy product that consists of equal parts whole milk and light cream. It typically contains around 10-12% fat, making it richer than milk but lighter than heavy cream. This balanced combination provides a creamy texture without being overly heavy and is often used in coffee, tea, and various culinary recipes to add a touch of richness.

In the context of alcohol and cocktails, Half and Half is used to create a smooth, creamy consistency in drinks. It can be an essential component in classic cocktails like the White Russian, where it helps balance the strong flavors of vodka and coffee liqueur, or the Mudslide, which combines vodka, coffee liqueur, and Irish cream liqueur. The dairy product adds a luxurious mouthfeel to these drinks, making them indulgent and satisfying.
