2 cup flour 1 cup sugar 1 tsp baking soda 1/4 tsp salt 2 large whole eggs 1 large egg yolk 1 tsp vanilla 1 Tbsp freshly grated orange zest 1 1/2 cup whole almonds, toasted lightly and coarsely chopped Egg wash: made by beating together 1 egg and 1 tsp water
Procedure
***************
In the bowl of an electric mixer, blend the flour, sugar, baking soda and
salt until combined well. In a small bowl, whisk together the whole eggs,
the yolk, vanilla and zest; add to flour mixture, beating until a dough is
formed. Add almonds.
Turn the dough onto a lightly floured surface, knead it several times and
halve it. Working on a large buttered and floured baking sheet, with foured
hand form each piece of dough into a flattish log 12 inches long and 2
inches wide. Arrange the logs at least 3 inches apart on the sheet, and
brush with egg wash.
Bake the logs in a preheated 300-degree oven for 50 minutes. Let them cool
on a rack for 10 minutes. On a cutting board, cut the logs crosswise on the
diagonal into 1/2 inch-thick slices.
Arrange the biscotti, cut sides down, on a baking sheet and bake in
300-degree oven for 15 minutes on each side.
