I need a full proof Lemon Meringue Pie recipe, please!!!!

PhotobucketMy hubby loves Lemon Meringue Pie and guess what….I cannot make a decent one!!! I have tried them all. This is what goes wrong.

1. The pastry does bake properly.
2. the filling is not tart enough.
3 …and my worst nightmare…the watery residue between the lemon layer and the egg white, yack!!!

So this is what I need:

1. A sublime shortcrust pastry.
2. A sweet, yet tart filling
3. NO< NO and I mean No watery layer or anything
4 …and a high meringue!!

Can anyone help, please!!!!
