A classic twice-baked treat featuring bright citrus zest and toasted nuts. These crisp Italian cookies are an evergreen favorite, designed to be dipped into coffee or tea any time of year.
Preheat oven to 350°F/177°C with rack in the center of the oven. Line a baking sheet with parchment paper.
Add the flour, baking powder and salt to a bowl, stir to mix.
To a separate bowl (or stand mixer) add the eggs and sugar. Beat until about 3 minutes until pale yellow. Add the flour mixture, pistachios and cranberries, vanilla and orange zest. Mix until combined. The dough will be sticky, allow to rest for 5 minutes.
Using wet hands, form the dough into a mound on the prepared baking sheet. Bake for 30 minutes until a little browned. Remove from the oven and allow to cool for 10 minutes.
Using a serrated knife, cut the dough into ¾ inch thick slices. Place them back onto the baking sheet and bake for 25 minutes until crisp.
