Paula Deen's Key Lime Pie recipe is a Southern twist on the classic dessert. The crust is made with graham crackers, sugar, and butter, and the filling is made with sweetened condensed milk, egg yolks, and fresh lime juice. The pie is baked until set and then chilled before serving. The whipped cream topping is optional but adds a creamy and sweet element to the tangy pie. Paula Deen also suggests serving the pie with a dollop of whipped cream and a slice of lime for garnish.
