In a mixing bowl, combine flour, sugar, and salt. Cut in the cold butter until the mixture resembles coarse crumbs. Add ice water, 1 tablespoon at a time, until the dough comes together.
Press the dough into a tart pan. Bake for 15 minutes, then let cool.
In another bowl, mix corn syrup, brown sugar, melted butter, beaten eggs, and vanilla extract. Stir in pecans.
Pour the filling into the cooled crust. Bake for 35 minutes or until set.
