Anything to get me away from the internet. Anything. I need something to kill time. Something productive. This is how I wound up in the kitchen for an hour & a half last night. I emerged smattered with powdered sugar, with lemon curd stuck to my jeans; the victor, lemon bars in hand! No better way to spend an hour & a half, trust me.
Ultimate Lemon Butter Bars, about 1 1/2 dzn. bars adapted from Rose Levy Beranbaum
Shortbread Base10 tbsp. unsalted butter, cold
2 tbsp. powdered sugar
2 tbsp. granulated sugar
1 1/4 c. bleached all-purpose flour
Lemon Curd Topping4 large egg yolks
3/4 c. sugar
2 - 2 1/2 large lemons, juiced
4 tbsp. unsalted butter, softened
pinch of salt
2 tsp. lemon zest
2 tbsp. powdered sugar for dusting

Cut the butter into 1-inch cubes, wrap it, & refrigerate. In a food processor with the metal blade, process the sugars for 1 minute or so, until the sugar is very fine. Add the butter & pulse until the sugar disappears. Add the flour & pulse until there are a lot of little moist crumbly pieces and no dry flour particles remain. Then, dump the mixture into a plastic bag & press it together. Remove the dough from the plastic bag & knead it lightly, until it holds together.
Place 1 oven rack in the middle of the oven. Preheat oven to 325°F. Pat the dough into an 8" x 8" foil lined pan. Use a fork to prick the dough all over. Bake for about 35 - 40 minutes or until the edges are lightly browned & the top is a pale golden (do not brown).

While the shortbread bakes, prepare the lemon curd. Have a strainer, suspended over a bowl, ready near the range. In a heavy noncorrodible saucepan, beat the egg yolks and sugar with a wooden spoon until well blended. Stir in the lemon juice, butter, & salt. Cook over medium-low heat, stirring constantly, for about 6 - 8 minutes, until thickened & resembling hollandaise sauce, which thickly coats a wooden spoon but is still liquid enough to pour. (
A candy thermometer will read 196°F.) The mixture will change from translucent to opaque and begin to take on a yellow color on the back of a wooden spoon. It must not be allowed to boil or it will curdle. (
It will steam above 140°F. Whenever steaming occurs, remove the pan briefly from the heat, stirring constantly to prevent boiling.) When the curd has thickened, pour it at once into the strainer. Press it with the back of a spoon until only the coarse residue remains. Discard the residue. Stir in the lemon zest.
Once the shortbread is baked, remove it from the oven, lower the temperature to 300°F., pour the lemon curd on top of the shortbread, and return it to the oven for 10 - 12 minutes. Cool the lemon curd–topped shortbread completely in the pan on a wire rack. Refrigerate the pan for 30 minutes to set the lemon curd completely before cutting into bars. Place the powdered sugar in a strainer & tap the strainer with a spoon to sprinkle a thick, even coating, entirely covering the lemon.
To remove from the pan, use the foil to lift out the lemon curd–covered shortbread onto a cutting surface. Use a long, sharp knife to cut the shortbread into around 1" x 2" bars. Wipe the knife after each cut.
