Lemon Chess Pie

Prepare, chill, and prebake a Foolproof Pie Shell . Reduce the oven temperature to 350º. Whisk together the sugar, cornmeal, and salt in a large mixing bowl. Add the eggs and egg yolk and whisk well. Whisk in the milk, melted butter, lemon juice, lemon zest, vanilla extract, and lemon extract if using. Then slowly pour the filling into the cooled pie shell. Bake the pie on the center oven rack for about 45 to 50 minutes, turning it 180 degrees halfway through. When done, the top will be dark golden brown, and the filling will be set except for the very center, which may jiggle slightly when you tap the pan. Cool the pie on a wire rack. Serve it at room temperature or cover and chill until serving time. Makes 8 to 10 servings.
