Lavender Shortbread Cookies

1 . Stage

In a medium bowl, cream together the butter, white sugar and confectioners' sugar until light and fluffy. Mix in the lavender, mint and lemon zest. Combine the flour, cornstarch and salt; mix into the batter until well blended. Divide dough into two balls, wrap in plastic wrap and flatten to about 1inch thick. Refrigerate until firm, about 1hour.

2 . Stage

Preheat the oven to 325 degrees F (165 degrees C). On a lightly floured surface, roll the dough out to 1/4 inch thickness. Cut into shapes with cookie cutters. Cookie stamps will work well on these too. Place on cookie sheets.

3 . Stage

Bake for 18 to 20 minutes in the preheated oven, just until cookies begin to brown at the edges. Cool for a few minutes on the baking sheets then transfer to wire racks to cool completely.
