Serving Size : 25
For the Bottom Layer:
1 Cup Flour Stirred With 1/8 Teaspoon Salt
1/2 Cup Sugar
1/2 Cup Cold Unsalted Butter, cut in pats
For the Topping:
2 Eggs
1 Egg Yolk
2/3 Cup Sugar
1-1/2 Tablespoons Flour
1 Teaspoon Grated Lemon Rind
1/3 Cup Fresh Lemon Juice
Confectioner’s Sugar, optional
Preheat the oven to 375. Grease and flour a 9×9 inch baking pan.
Make the bottom layer:
Put the flour and sugar in the bowl of a food processor and process to combine. Add the butter and process until the mixture clumps, scraping down the bowl several times. Pat the dough evenly over the bottom of prepared pan. Bake 14-16 minutes, until the top is dry-looking and lightly browned at the edges. Place the pan on a wire rack to cool. Reduce the oven temperature to 350.
Make the topping:
Put the eggs, egg yolk, sugar, flour, lemon rind, and lemon juice in the food processor bowl (there is no need to wash the bowl after making the bottom layer) and process until well blended. Pour the topping over the cooled dough in the pan.
Bake for 16-18 minutes longer, until the top is dry and covered with tiny craters (broken bubbles), and the edges are lightly browned.; do not overcook. Let the pan cool completely on a wire rack. If you like, sprinkle with 1 or 2 tablespoons of confectioners’ sugar sifted through a fine strainer. Run a sharp knife around the edge of the pan, then cut into 25 squares (5 squares by 5 squares) wiping the knife blade between cuts.
