Combine all ingredients, from sugar to cinnamon whiskey. Mix well. Pour into unbaked pie shell.
Bake for 45 minutes to 1 hour. Check your crust at 45 minutes and if too brown, cover with foil until the pie is fully baked in the center. A knife inserted should come out clean.
Serve with your favorite whipped topping or vanilla ice cream. In true Texas form, use Blue Bell!
Notes
Alternatively, you can use 1/2 cup light corn syrup and 1/2 cup dark corn syrup to achieve the rich mahogany color of classic pecan pies.
