‘Tis the season for lemons. Actually, late winter is the season for lemons, but happily the season spills into spring, offering up bushels of citrus which beget light and lovely desserts, such as these Lemon Bars. Lemon Bars are a family favorite, a quintessential childhood treat that pleases adults and kids alike. The key to a good lemon bar, in my book, is that the filling must be intensely lemony packing a wallop of tart, with just enough sugar, but not so sweet that it’s cloying. The final touch is a pinch of sea salt, which keeps the sweetness in check and allows the lemon to shine through.
This recipe is adapted from and inspired by many sources, including Ina Garten and, most recently, Lucas’ Lemon Bars from Food52, as well as my personal weakness for sea salt. Makes 32 two-inch square bars.
2 cups all-purpose flour
1/2 cup confectioner’s sugar, plus extra for dusting
1/2 teaspoon kosher salt
1 cup unsalted butter, slightly softened but still cool, cut in cubes
4 large eggs
1 1/4 cups granulated sugar
2/3 cup freshly squeezed lemon juice
1/4 cup all-purpose flour, sifted
1 tablespoon finely grated lemon zest
1/4 teaspoon kosher salt
Sea salt flakes, such as Maldon or Fleur de Sel, for garnish
Preheat the oven to 350 F. Butter a 9 inch by 13 inch baking pan. Line with parchment and butter the parchment. Combine the pastry ingredients in the bowl of an electric mixer fitted with a paddle attachment. Mix until the dough resembles coarse lumps and just begins to come together. Dump the dough into the prepared pan and, with your fingers, evenly press the dough to cover the bottom of the pan. Bake the crust until it just begins to turn golden, about 20 minutes. Remove from oven.
Whisk the filling ingredients together in a large bowl until blended. Evenly pour over the crust. Return the pan to the oven and bake until the filling is set but not coloring, about 25 minutes. Remove and cool completely on a rack. Cut into bars. Dust with confectioner’s sugar and lightly sprinkle with sea salt flakes.
