American key lime pie is a traditional dessert with its roots in American cuisine, particularly popular in the southern United States. This dessert combines the characteristic acidity of the lime with a creamy and fresh texture that makes it ideal for warm climates. In some Latin American countries, although not as common, it can be found under similar names like "lemon tart" or "lemon pie," adapting to local ingredients and flavor preferences.
The original recipe dates back to the early 20th century and is characterized by the use of unflavored gelatin which provides a firm and light consistency. It is a refreshing and less heavy alternative to other cream or cheese-based desserts. The presentation is usually very attractive, adorned with grated lime zest and pistachios, giving it a special and elegant touch.
