CITRUS BUTTER COOKIES RECIPES

Steps:

• Preheat oven to 350 degrees.Cream butter and sugar until combined. Add egg yolks and mix until combined (set whites aside for the icing.) Add the zest and the flour and mix until just combined, then add juice and mix until combined. Scoop out heaping teaspoons of dough, then roll them into balls between your hands. Place on a cookie sheet and bake for 13 minutes. Remove from the oven and keep on the cookie sheet for 3 to 4 minutes. Remove from the pan with a spatula and allow to cool completely before icing.To make the icing, combine 1 egg white with the rest of the icing ingredients. Whisk thoroughly until combined, adding either more powdered sugar or more juice until it reaches a pourable but still thick consistency. Drizzle the icing across the cookies in several lines, then do it again in the other direction. Sprinkle with extra zest before the icing sets.

Steps:

• Place the butter in the bowl of an electric mixer fitted with the paddle attachment and beat on medium until smooth. Add the confectioners' sugar and beat until smooth and silky. Beat in 1 egg yolk, then the salt, vanilla, and lemon zest. Reduce mixer speed to low and add the flour, beating just until incorporated. Do not over-beat. Turn the dough out onto a work surface. Divide dough in two and wrap each piece in plastic wrap. Refrigerate for 30 minutes.
• Working on a smooth surface, form each piece of dough into a log 1 to 1 1 /4 inches in diameter. Wrap logs in plastic wrap and refrigerate for 2 hours. Can be prepared up to this point and kept, well wrapped in the refrigerator for up to 3 days or frozen for up to 1 month.
• Place one rack in the upper third and one in the lower third of the oven. Preheat oven to 350 degrees. Line two baking sheets with parchment paper; set aside.
• Whisk the remaining egg yolk in a small bowl until smooth. Spread sugar out on a piece of wax paper. Remove the logs from refrigerator, unwrap, and brush lightly with the egg yolk. Roll logs in the sugar, pressing to adhere. Slice crosswise 1/4-inch-thick using a sharp knife. Place on prepared baking sheet, leaving about 1/2-inch between cookies.
• Bake until set but not brown, 12 to 14 minutes. Transfer cookies to cooling rack until room temperature. Will keep stored in an airtight container, at room temperature, for up to 5 days.
