Combine flour; sugar, rind, and cornmeal. Add eggs, milk, butter, and juice then beat thoroughly. Turn into crust, bake at 350 F for 25-30 minutes, or until set. To make meringue: raise oven temp to 400 F. Beat whites till foamy and doubled in volume then beat in lemon juice. Beat in sugar 1-2 T at a time until stiff peaks form and mixture is thick and glossy. Spread on hot pie. Bake in 400 F oven for 8 minutes, until golden brown. Annette Thompson.
