Preheat oven to 400°F.
Cream butter and sugar until fluffy; add egg and orange peel.
Mix remaining ingredients in a separate bowl and stir into batter, do not overmix.
Gather the dough until smooth and divide into 8 equal portions.
Roll each portion into a long thin roll 1/2 inch in diameter.
Cut the roll into small pieces - approx 22 pieces per roll.
Roll into small nuts (if you are lazy or short of time you can skip this step, although rolling make for a nicer looking cookie).
Place the 'nuts' on cookie sheets lined with parchment paper.
Bake for 10 minute.
