1 store-bought graham cracker crust (They now come in 2 sizes. If you get the smaller size, use these proportions. If you get the larger one, I have been doubling it for a thicker pie)
1 can sweetened condensed milk
1/2 C Key Lime Juice
3 large egg yolks
1/4 cup buttermilk.
Beat ingredients together. Bake at 325 for 20-25 minutes. Pie will be a little jiggly. Cool on a rack. Cover with plastic wrap (might want to spray the plastic wrap). Put in the freezer for 4-6 hours.
