This key lime pie uses a crisp graham cracker base and a tangy baked filling of egg yolks, condensed milk and fresh lime. The source omits condensed milk even though its method depends on a thick filling, so it is included here to make the pie work. Bake only until the center has a slight wobble, then chill thoroughly before slicing. Use pasteurized eggs if adding a separate meringue topping. Heat oven to 175°C (350°F); mix crumbs and butter, press into a 23 cm pie plate and bake 8 minutes; cool slightly. Whisk egg yolks and lime zest until thick; whisk in condensed milk, then lime juice until smooth. Pour filling into crust and bake 15 to 18 minutes until edges set and center has a slight wobble.
