Preheat oven to 350° F.
Roll out pie crust pastry and place in pie pan, making extra-high, fluted rim.
In large mixing bowl, lightly beat eggs by hand.
Add lemon juice, corn syrup, vanilla, brown sugar, nuts, and butter.
Stir by hand long enough to begin dissolving sugar but not enough to incorporate air into filling. Do not beat.
Pour mixture into pie crust.
Bake on cookie sheet until center of pie no longer is loose and nuts are browned, approx. 1 hour.
Let pie come to room temperature before cutting.
