Semolina-Corn Sablés

In a food processor, pulse the almond flour, confectioners' sugar, semolina, cornstarch and salt. Add the butter and pulse until smooth. Add the egg white and pulse until incorporated. Add the corn nuts and pulse just until blended. Scrape the dough (it will be very soft) onto a sheet of plastic wrap and top with another sheet. Pat the dough into a rough 10-by-8-inch rectangle and transfer to a baking sheet. Freeze until very firm, 30 minutes.

Preheat the oven to 325° and line a baking sheet with parchment paper. On a floured surface, unwrap the dough and trim it to an even 10-by-8-inch rectangle. Cut lengthwise into 3 strips and then crosswise into 1-inch-wide rectangles. Arrange on the baking sheet, about 1/2 inch apart.

Bake the cookies for 30 minutes, until golden; transfer to a rack to cool. Serve.
