3. Divide each dough into 4 logs, about 1 inch in diameter, and reserve about 10 grams of each dough to make the dots. Press one side of each log with your thumb to make a comma shape. Cover and chill 1 hour until firm.
   
4. Dust a work surface lightly with flour. Place one orange dough log with round side down on the work surface. Brush the side lightly with water and turn the chocolate dough log on top of the orange dough, creating the yin-yang pattern. Gently roll the log until round. Repeat with the remaining logs. Wrap and chill 1-2 hours until firm.
   
   
5. Preheat the oven to 175C/350F. Cut the cookie logs into 5mm thick slices. Arrange the cookies on a parchment paper lined baking pan, about an inch apart. Pinch a bit of reserved chocolate dough, and roll it into a small round ball. Gently press it into the orange part of the cookies. Do the same with the reserved orange dough and press them into the chocolate part of the cookies. Bake in the center of preheated oven for about 12 minutes. Cool the cookies on the rack.
