LEMON BARS

Adapted from Cook's Illustrated

Ingredients:

Base:
1 c (5 ox) AP flour
1/4 c (1 3/4 oz) granulated sugar
1/2 t salt
8 T unsalted butter, melted

Filling:
1 c (7 oz) granulated sugar
2 T AP flour
2 t cream of tartar
1/4 t salt
3 large eggs plus 3 egg yolks
2 t grated lemon zest
2/3 c lemon juice (4 lemons)
4 T unsalted butter, cut into 8 pieces

2 T confectioners sugar


Methodology:

Combine the flour, granulated sugar and salt, and stir in the butter.  Press into a greased 8"x8" baking pan and bake at 350°F for 40 minutes, or until golden brown.  Remove from the oven, but leave oven on.

Add all filling ingredients but the butter to a saucepan and heat over medium-low heat, whisking constantly.  Once the filling begins to thicken, remove from heat and whisk in the butter, mixing until smooth.

Strain the filling onto the base and return to the oven for an additional 10 minutes.  Remove from oven and cool.  Dust with confectioners sugar, slice and serve.

***edited to add note: these turned out extremely sour, and the topping was quite liquid-y***
