1 1/4 cups unsifted flour
1 stick unsalted butter, cut into slices
1 cup plus 2 tablespoons sugar
2 tablespoons finely grated lime zest
Pinch of salt
1/2 cup fresh lime juice
2 large eggs
1/2 teaspoon baking powder Confectioners' sugar
Preheat oven to 375 degrees. Grease an 8-inch square baking pan.
Blend 1 cup flour, butter, 2 tablespoons sugar, 1 tablespoon lime
zest, and salt with a pastry blender until mixture forms a loose
paste. Turn out into the baking pan and pat evenly onto the
bottom, forming a 1/2-inch edge along the pan sides. Bake
until the crust is pale golden, 15 to 20 minutes. Remove
from oven, then reduce the temperature to 350 degrees.
Cool crust 10 minutes. While the crust cools, whisk together
remaining flour, sugar, and lime zest along with lime juice,
eggs, and baking powder. Pour the filling onto the partially
cooked crust, then bake until filling is set, 25 minutes. Cool
completely, then chill at least 2 hours before cutting.
Sprinkle with confectioners' sugar.
