Key lime pie is a classic dessert that originated in the Florida Keys. It is made from a mixture of lime juice, sweetened condensed milk, and eggs, which are poured into a crust made of graham crackers, sugar, and butter. The filling is then baked until set and topped with whipped cream or meringue before serving. Key lime pie is known for its tangy, sweet flavor and light, refreshing texture. It is a popular dessert choice for summer gatherings, picnics, and potlucks, and can also be made in individual portions for an easy, on-the-go treat.
