- 1 cup unsalted butter, cubed
 - 1 cup white sugar
 - 2 egg yolks
 - 2 tablespoons grated orange zest
 - 1/2 teaspoon ground nutmeg
 - 1/4 teaspoon salt
 - 2 1/4 cups cake flour
 - 2 tablespoons poppy seeds
 
- Combine the butter, sugar, egg yolks, lemon or orange zest, nutmeg and salt. Beat until light and fluffy.
 - Sift the flour, then add it and the poppy seeds to the butter mixture. Mix until just combined.
 - Divide dough into 4 equal parts. Form each piece into a 2 inch diameter cylinder and wrap in plastic and refrigerate for 2 hours or until firm. At this point you can freeze the dough for later use.
 - Preheat oven to 350 degrees F (175 degrees C).
 - Cut dough cylinders into 1/4 inch thick slices and place on ungreased baking sheets. Bake at 350 degrees F (175 degrees C) for 9 minutes. Let cookies cool on sheets for 2 minutes, then transfer to wire racks to cool. Once cool, store in an airtight container.
