Mix well one cup light corn syrup with 3 well-beaten eggs, a cup of sugar, a half stick of melted butter, and a tablespoon of pure vanilla extract. Stir in a cup and a half of chopped pecans. Pour filling into an unbaked 8-in. pie crust. I always top it with pecan halves and lightly cover the pie with foil to prevent scorching. Place pie on a rimmed baking sheet in the center rack of a 350 oven. Bake for at least an hour, until center is firm and springy. Cool very well before serving.
