The official Key Lime Pie is made with simple ingredients. Key lime juice, sweetened condensed milk, and raw egg yolks are beaten together until thick and creamy.  The pie is baked for a short time and then refrigerated to set up. Top with whipped cream and garnish with slices of Key limes before serving this sweet and tangy lime pie recipe.
