Ingredients

• 0.5 teaspoon cinnamon 
• 1.3 oz cranberries dried
• 1 large eggs lightly beaten
• 1.5 cups flour all-purpose
• 0.3 cup granulated sugar 
• 0.5 teaspoon orange zest fresh finely grated
• 0.5 cup pistachios red shelled ()
• 0.3 teaspoon salt 
• 0.3 cup decorative sugar (preferably coarse)
• 0.8 cup butter unsalted softened

Equipment

• bowl
• baking sheet
• baking paper
• oven
• plastic wrap
• hand mixer
• aluminum foil
• wax paper
• spatula

Directions

1. Stir together flour, cinnamon, and salt in a bowl.
2. Beat together butter, granulated sugar, and zest in a large bowl with an electric mixer at medium-high speed until pale and fluffy, about 3 minutes. Reduce speed to low and add flour mixture in 3 batches, mixing until dough just comes together in clumps, then mix in pistachios and cranberries. Gather and press dough together, then divide into 2 equal pieces. Using a sheet of plastic wrap or wax paper as an aid, form each piece of dough into a log about 1 1/2 inches in diameter. Square off long sides of each log to form a bar, then chill, wrapped in plastic wrap, until very firm, at least 2 hours.
3. Put oven racks in upper and lower thirds of oven and preheat oven to 350°F. Line 2 large baking sheets with parchment paper.
4. Brush egg over all 4 long sides of bars (but not ends).
5. Sprinkle decorative sugar on a separate sheet of parchment or wax paper and press bars into sugar, coating well.
6. Cut each bar crosswise into 1/4-inch-thick slices, rotating bar after cutting each slice to help keep square shape. (If dough gets too soft to slice, freeze bars briefly until firm.) Arrange cookies about 1/2 inch apart on lined baking sheets.
7. Bake cookies, switching position of sheets halfway through baking, until edges are pale golden, 15 to 18 minutes total.
8. Transfer cookies from parchment to racks using a slotted spatula and cool completely.
9. •Dough bars can be chilled up to 3 days or frozen, wrapped in plastic wrap and then foil, 1 month (thaw frozen dough in refrigerator just until dough can be sliced).•Cookies keep in an airtight container at room temperature 5 days.
