3/4 stick butter, softened
1/4 c. powdered sugar
1 c. plus 3 tbsp. all-purpose flour
3 eggs
1 c. granulated sugar

Meanwhile, combine eggs, sugar, rind, juice and remaining 3 tablespoons flour; mix well. Pour lemon mixture over hot crust. Bake 15 to 20 minutes longer until firm. Cool. If desired, sprinkle with powdered sugar when still warm.
