8 ounces unsalted butter, 2 sticks
1 1/2 cups sugar
3 tablespoon orange rind finely grated
2 tablespoons vanilla extract
6 cups all-purpose flour
1 tablespoon baking powder
1 teaspoon salt
6 eggs beaten
1/4 cup amaretto
2 cups almonds, blanched ,toasted, sliced
2 cups chocolate chips

Preheat oven to 350 degrees. In an electric mixing bowl, combine butter, sugar, orange peel and vanilla; beat until light and creamy. Sift together the dry ingredients. With the mixer on slow, add dry ingredients to butter mixture and mix until thoroughly combined. Slowly add eggs and amaretto. Add almonds and chocolate just until combined. Remove dough to a floured surface and form into two flat logs about 4 inches wide and the length of your cookie
sheet. Lay the logs onto buttered sheets and place on lower rack of the oven. Bake until lightly browned, about 45 minutes.

Remove to a rack to cool. With a serrated knife, cut the loaves into half-inch slices, placing the cut slices flat on the cookie sheet. To make crisp, return them to the lower rack of the oven and cook until golden, 15-20 minutes. Remove the slices to a wire rack to cool then store in an airtight container. Use a decorative tin for gift giving.
NOTE: If the biscotti lose their crispness, repeat the crisping stage
