Pineapple syrup is a sweet, flavorful liquid made from the juice and sometimes the flesh of pineapples, combined with sugar to create a thick consistency. It captures the tropical essence of the fruit and is commonly used as an ingredient in various culinary applications, including desserts and beverages.

In the context of alcohol and cocktails, pineapple syrup acts as a versatile mixer that adds both sweetness and a distinct tropical flavor. It pairs particularly well with rum, making it a popular choice for tiki-style cocktails like the Piña Colada and the Mai Tai. Additionally, it can be used to enhance the flavor profile of other spirits, such as vodka, gin, and tequila, bringing a refreshing and exotic touch to drinks.
