In a large mixing bowl, cream together softened butter, sugar, and salt until light and fluffy, about 3-5 minutes.

Beat in the egg, orange zest, orange juice, and lemon extract until well combined.

Gradually add all-purpose flour to the wet mixture, stirring gently just until combined.

Divide the dough into two equal halves, shape into disks, and refrigerate for at least 1 hour.

Preheat your oven to 375°F (190°C) while the dough chills.

Roll out one disk to about ¼ inch thick, use cookie cutters to cut shapes, and place them on greased baking sheets.

Bake for 8-10 minutes, or until edges are lightly golden.

Cool on wire racks for about 5 minutes, then ice with confectioners’ sugar and milk, adding food coloring if desired.
