In a large mixing bowl, combine the first 6 ingredients and mix with an electric mixer.
Add the melted butter and mix quickly with mixer.
Place pecans halves in the pie crust in the 10-inch pie plate. Pour syrup mixture over the nuts.
Bake in oven at 350 degrees F for 50 minutes. Check on it at 40 minutes. At 50 minutes, the syrup should be bubbling up around the pecans, which means it's done. Remove pie from oven and let cool on rack for an hour or two.
Refrigerate pie for several hours or overnight. Refrigeration thickens pie syrup and intensifies flavor.
Serve a la mode with a scoop of good quality vanilla ice cream.
