Ingredients

5 ounces shortbread cookies, broken 

3 ounces shelled unsalted pistachios (2/3 cup) 

1/4 cup sugar 

1/2 teaspoon coarse salt 

2 ounces (4 tablespoons) unsalted butter, melted 

Preparation

Preheat oven to 350 degrees. Pulse cookies in a food processor until crumbs form. (You should have 1 cup.) Process with pistachios, sugar, and salt, until fine crumbs form. Add butter, and process until mixture holds together.

Press crumb mixture evenly into bottom and up sides of a 9-inch fluted tart pan with a removable bottom. Refrigerate for 15 minutes. Bake until golden brown, 17 to 20 minutes. Transfer to a wire rack, and let cool.
