Lime Curd Bars with Coconut Crust
Preheat the oven to 350 degrees F. Line a 9-by-13-inch baking dish with aluminum foil, overhanging the edges by 1 inch. In a mixer fitted with the paddle attachment, beat the butter and brown sugar until fluffy, 3 to 4 minutes. Add the flour, half of the lime zest, coconut and half of the salt and mix until the dough just holds together. Press into the pan and prick with a fork. Bake until golden, 20 to 25 minutes.
In the mixer, combine the granulated sugar, cornstarch, baking powder and remaining lime zest and salt. Slowly beat in the eggs and lime juice. Pour into the crust. Bake for 20 to 25 minutes. Cool and then refrigerate until set, 1 to 2 hours. Cut into 24 bars and dust with confectioners’ sugar and lime zest. Makes 2 dozen bars.
