If I had to name a favorite baking ingredient, it would be a lemon, and, in my opinion, the best way to show off its citrusy sweet-tart flavor is a lemon bar. These tiny (or not so tiny) squares are all about the citrus. A buttery shortbread crust anchors a squidgy thick wedge of puckery filling, simply topped with dusting of sugar. A pinch of sea salt is a nice finishing touch, balancing the sweetness and letting the lemon shine through. These bars are thoroughly addictive and guaranteed to brighten your day. One bar will never be enough.
Lemon Bars with Sea Salt
This recipe is adapted from and inspired by many sources, including Ina Garten, Food52, and my personal weakness for lemon – and sea salt. Makes 32 (2-inch) square bars.
2 cups all-purpose flour
1/2 cup confectioners’ sugar
1/2 teaspoon kosher salt
1 cup unsalted butter, slightly softened but still cool, cut into 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
1. Preheat the oven to 350°F. Butter a 9-by-13-inch baking pan, then line the pan with parchment and butter the parchment.
2. Combine the shortbread 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.
3. Bake the crust until it just begins to turn golden, about 20 minutes. Remove from oven, but do not turn off the oven heat.
4. Whisk the filling ingredients together in a large bowl until blended, then 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.
5. Cut into bars. Dust with confectioners’ sugar and lightly sprinkle with sea salt flakes before serving.
