Citrus Egg Yolk Cookies

• 1 1/2 cups white sugar
• 1 cup butter, softened
• 6 egg yolks
• 1 teaspoon vanilla extract
• 1/2 teaspoon lemon extract
• 1/2 teaspoon orange extract
• 2 1/2 cups all-purpose flour
• 1 teaspoon baking soda
• 1 teaspoon cream of tartar

1. Preheat oven to 350 degrees F (175 degrees C). Grease or line baking sheets with parchment paper.
2. Beat sugar and butter together in a bowl with an electric mixer until light and fluffy. Beat egg yolks, vanilla extract, lemon extract, and orange extract together in another bowl. Add egg yolk mixture to butter mixture; beat well.
3. Sift flour, baking soda, and cream of tartar together in a bowl. Stir flour mixture into butter mixture until dough is well-blended. Roll dough into walnut-size balls and place on prepared baking sheets. Press dough balls to slightly flatten.
