Emeril Lagasse's Key Lime Pie recipe is a slightly more complex version of the dessert. The crust is made with graham crackers, sugar, and butter, and the filling is made with sweetened condensed milk, egg yolks, fresh lime juice, and lime zest. 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. Emeril also suggests serving the pie with a raspberry sauce for added flavor.
