Key Lime Pie is a tangy and zesty dessert that transports your taste buds to the sunny shores of Florida, where the refreshing flavors of key limes meet the indulgence of a buttery graham cracker crust. This iconic dessert is a celebration of tropical flavors and culinary ingenuity. With its creamy filling and vibrant citrus twist, Key Lime Pie has become a staple in dessert menus across the world. In this recipe, we’ll explore the history of Key Lime Pie, the significance of key limes in culinary traditions, and guide you through the step-by-step process of creating this quintessential dessert—a treat that captures the essence of summer in every bite.

The origins of Key Lime Pie are rooted in the Florida Keys, where the abundance of key limes and condensed milk inspired the creation of this beloved dessert. The recipe’s history is closely tied to the arrival of sweetened condensed milk in the late 19th century, which made it possible to create a pie filling without relying on fresh milk or cream. Key Lime Pie quickly gained popularity as a refreshing and easy-to-make dessert, becoming a cherished part of Southern cuisine and eventually gaining fame beyond regional borders.

Key limes, also known as Mexican or West Indian limes, are smaller and more tart than the traditional Persian limes commonly found in grocery stores. They are native to Southeast Asia but have become synonymous with the Florida Keys due to their historical connection to the region. Key limes are prized for their distinct flavor and are often used in a variety of dishes, from savory to sweet, to add a burst of citrusy brightness.
