Macadamia and chocolate biscotti

1. Preheat oven to moderate, 180°C. Lightly grease and flour an oven tray.
   
   
2. Sift flour and soda into a large bowl. Stir in macadamias, sugar and chocolate.
   
   
3. In a jug, dissolve coffee powder in water. Cool slightly. Whisk in eggs, Grand Marnier and zest.
   
   
4. Make a well in the centre of the dry ingredients. Add egg mixture and mix
   to a firm dough.
   
   
5. Turn dough onto a lightly floured surface. Cut in half and form into 2 logs, about 5cm wide. Place on prepared tray and bake 20-25 minutes.
   
   
6. Allow to cool. Using a serrated knife, slice into 0.5cm pieces. Arrange on trays
   and bake a further 5-10 minutes, until crisp.
   
   
7. Transfer to a wire rack to cool. Store in an airtight container.
