1/2 lb unsalted butter at room temp
1/2 c sugar
2 c flour
1/2 t salt

Instructions
                
                Crust:
Cream the butter and sugar until light and fluffy.  In a separate bowl, combine the flour and salt - with the mixer on low, add to the butter until just mixed.  Dump the dough onto a well-floured board and gather into a ball.  Flatten the dough with floured hands and press into a 13x9 greased pan (or jelly roll pan).  Chill for 30 minutes.  Preheat oven to 350.
Filling:
Whisk together the eggs, sugar, lemon zest, lemon juice and flour.  Pour over crust and bake for 30-35 minutes (20-25 for jelly roll pan)until the filling is set.  Cool to room temp and cut into bars.  Dust with powdered sugar.
