Orange Pistachio Choc Chip Biscotti

....or whatever you want to call it.  Pistachio orange choc chip.  Chocpistachiochiporange.  I like that better.

Orange Pistachio Chocolate Chip Biscotti

2 3/4 cups flour
1 1/2 teaspoons baking powder
1/2 teaspoon salt
1 1/2 cups sugar
3 eggs
1 tablespoon Grand Marnier or other orange liqueur
1 teaspoon orange extract [optional]
6 tablespoons butter, melted
1 cup dark chocolate chips
3/4 cup chopped pistachios
2 tablespoons orange zest
1 1/2 cups dark chocolate (chips or chopped - for melting/dipping)

Heat oven to 325F.  In a large bowl, whisk together flour, sugar, salt, and baking powder.  Add eggs, orange zest, liqueur and extract (if using) and stir well.  Add melted butter and stir until combined.  Stir in chocolate chips and pistachios.  Use your hands to mix if needed (it'll be sticky).

Turn dough onto lightly floured surface.  Divide dough into three equal portions.  Shape each portion into a 14" log.  Place logs on a baking sheet lined with parchment or Silpat, 3" apart.  Flatten logs slightly until about 1 1/4" wide.

Bake for 30 minutes or until firm and light brown.  Remove from oven and place baking sheet on wire rack; cool for 15 minutes.

Transfer logs to cutting board.  Using a sharp serrated knife, cut each roll on the diagonal in 1/2" slices.  Place slices cut side down back onto lined baking sheet.  Bake for 15-20 minutes or until crisp, golden brown.  Transfer to wire rack and cool completely.

Put chocolate for dipping into a microwave-safe bowl and heat in minute increments at half power, stirring between each time, until melted.  Dip each biscotti into melted chocolate, allowing excess to drip back into the bowl.  Place dipped biscotti on wax paper (choc side down) and allow to set.
