1 cup all purpose flour
1/4 cup confectioners sugar
1/4 tsp sea salt
1 stick cold butter
for the lemon filling:
1 1/4 cups granulated sugar
1/4 cup all purpose flour
2 tsp lemon zest
2/3 cup freshly squeezed lemon juice
additional confectioners sugar for dusting
Preheat oven to 350. To make the crust, combine the confectioners sugar, flour and sea salt in a large bowl. Cut in the cold butter and work with your fingers until the mixture resembles cornmeal. Press into a greased nine inch pan and bake for 20 minutes, or until golden.
To make the filling, whisk together the granulated sugar and flour in a bowl. Add the eggs, one at a time, whisking well after each addition. Add the zest and the juice and mix until everything is smooth and combined. Pour filling over hot crust and return to oven to bake for another twenty minutes. When done, the filling will no longer jiggle. Let cool completely in the pan before slicing and dusting with powdered sugar.
