Making lemon bars allows me to use 2 of my favorite kitchen gadgets - a Microplane rasp and a citrus reamer....
For the crust:
1/2 pound unsalted butter, at room temperature
1/2 cup granulated sugar
2 cups flour
1/8 teaspoon kosher salt
For the filling:
3 cups granulated sugar
2 tablespoons grated lemon zest (4 to 6 lemons)
1 cup freshly squeezed lemon juice
1 cup flour
Confectioners' sugar, for dusting
Preheat the oven to 350 degrees F.
For the crust, cream the butter and sugar until light in the bowl of an electric mixer fitted with the paddle attachment. Combine the flour and salt and, with the mixer on low, add to the butter until just mixed.
Press the dough into a 9 by 13 pan.
Bake the crust for 15 to 20 minutes, until very lightly browned. Let cool on a wire rack. Leave the oven on.
For the filling, whisk together the eggs, sugar, lemon zest, lemon juice, and flour. Pour over the crust and bake for 30 to 35 minutes, until the filling is set. Let cool to room temperature.
Cut into triangles and dust with confectioners' sugar.
