Cornmeal Lime Shortbread Fans

Preparation

1. Step 1

   Heat oven to 325 degrees. Grate 1 teaspoon zest from the limes. (You can usually get 1 teaspoon from 1 lime, but you may need to grate some zest off the other.) Add to a food processor.

2. Step 2

   Add flour, cornmeal, sugar and salt and pulse once or twice to combine. Add butter and pulse until the mixture resembles fine crumbs. Pulse a few more times until some of the crumbs start to come together, but don’t overprocess the dough. It should be somewhat crumbly and not form a ball. (Alternatively, you can mix this in a bowl using two knives, or use a pastry cutter to mix the butter into the flour.)

3. Step 3

   Press the dough into an even layer in an ungreased, fluted 9-inch tart pan with a removable bottom or in a 9-inch pie pan. Prick the dough all over with a fork. Bake until golden brown, about 40 to 50 minutes.

4. Step 4

   Transfer to a wire rack to cool. Using a butter knife, cut the shortbread into 12 wedges while still warm.

5. Step 5

   Make the glaze: Halve the zested lime and squeeze 1 tablespoon juice into a small bowl. Whisk in confectioners’ sugar and, if you like, more lime juice to taste. (More lime juice will make the glaze thinner and more tart, while less lime juice yields a thicker, sweeter glaze.) Drizzle glaze over the cooled shortbread, then zest the second lime over the icing before it sets. (Use a citrus zester, if you have one, or a regular zester, if you don’t.)
