Spread meringue along the bottom and the sides of the pie dish.

Bake at 300 degrees F. for 45-60 minutes or until crust is dry looking. The crust will puff up as it cooks. As soon as you remove it from the oven it will begin to crack and fall. That is what it is suppose to do, making the perfect space for all the lovely lemon filling.
Allow crust to cool while you make the filling.

How To Make Lemon Angel Pie
While the meringue crust is baking, you can make the filling.

Combine the egg yolks, sugar, lemon juice, lemon rind and salt into a microwave safe container and mix. Make sure the container is big enough as the mixture will expand as it cooks.
Cook the mixture until thickened in microwave for 4 minutes (stir every 30 seconds) and allow to cool. You can also cook the mixture on the stove top. Stir constantly until thickened.
