1 ½ c.  roasted cashews (about 7 oz.) 
      2 c.  unbleached all-purpose flour 
      1 c. sugar 
      1 tsp.  baking soda 
  ¼ tsp. salt 
      4 large  eggs (divided)  
      1 T.  freshly grated orange zest 
      1 tsp.  vanilla 
    1  tsp. water  | 
    Preheat  oven to 300 degrees and grease a large baking sheet (or place a Silpat on the sheet). 
      Coarsely  chop cashews.  Stir flour, sugar, baking  soda and salt together.  Beat 3 eggs,  zest and vanilla with electric mixer until just combined.  Stir in flour mixture and beat until a stiff  dough is formed.  Stir in cashews. 
      Beat  together water and remaining egg to make a wash.  On baking sheet with floured hands form dough  into two 12” long logs and flatten slightly.   Brush logs with egg wash.  Bake  logs in middle of oven until golden, about 50 min.  Cool logs on baking sheet on a rack 10 min. 
      On  a cutting board with a serrated knife diagonally cut logs into roughly 1/3”  thick slices.  Arrange biscotti, a cut  side down, on baking sheet and bake in middle of oven until crisp, about 15  min.  Cool on a rack.  Store airtight. |
