Key Lime Tart
Key lime tarts are a delicious and tangy dessert made with key limes, a variety of limes that are smaller and more aromatic than the typical Persian limes. These tarts are popular in the United States, particularly in the Florida Keys, where key limes are abundant and have given the dessert its name. Key lime tarts are known for their sweet and tart flavor, as well as their creamy and smooth filling that is both decadent and refreshing, perfect for any season. If key limes are not readily available, Persian limes, also known as regular super market limes also work perfectly.
