Preheat the oven to 350°F (175°C).
Prepare the pie crust by combining flour, butter, and sugar in a large bowl.
Add the egg yolk and ice water, mixing just until combined.
Form the dough into a disc, wrap in plastic wrap, and refrigerate for 30 minutes.
Roll out the pie dough on a floured surface and fit it into a 9-inch pie pan.
Prick the bottom of the crust and bake for 15 minutes until lightly golden.
In a mixing bowl, combine Meyer lemon juice, sweetened condensed milk, eggs, and lemon zest.
Pour the filling into the pre-baked crust and bake for another 15-20 minutes.
Allow the pie to cool to room temperature, then refrigerate for at least 2 hours.
Serve with whipped cream or a sprinkling of lemon zest if desired.
