Prick the bottom of the pie shell with a fork and bake for 10 minutes. Remove from oven and cool completely. Beat together the eggs, corn syrup, sweetened condensed milk, half & half, butter & nut extract, and salt until well blended. Stir in the chopped peanuts. Pour into pie shell and bake for 45 minutes or until center is set (halfway through baking process, cover pie edges with foil to prevent over-browning). Remove from oven and cool. Drizzle pie with caramel dessert topping before serving. Makes 8 servings.
