1 - 3teaspoonslemon zestdepending on how lemony you want them
2cupsall-purpose floursifted
Lemon Icing
1 ¼cupspowdered sugar
3Tablespoonsfresh lemon juice(juice from 1 large lemon)

Instructions
Shortbread Cookies
In a large mixing bowl, cream together the butter, powdered sugar, salt, lemon juice, and lemon zest until light and fluffy.
Beat in the flour until just combined. Do not overmix.
Using your hands, bring the mixture together to form a dough. Wrap the dough in plastic wrap and refrigerate for 30 minutes.
Preheat the oven to 350°F. Line several cookie sheets with parchment paper.
Remove the dough from the fridge, and roll it out on a floured surface to between ¼" in thickness. Using a cookie cutter (about 2" diameter), cut out your shortbread into shapes. Place on the prepared cookie sheets.
Bake for 15 - 17 minutes or until the edges are lightly golden.
Remove from the oven, place on a wire rack, and let cool completely.
While the cookies are cooling, prepare the lemon icing.
Drizzle or spread the icing over the cookies, and sprinkle with fresh lemon zest, if desired.
Lemon Icing:
Combine powdered sugar and lemon juice in a medium bowl and whisk. Add more lemon juice if needed. The glaze should be a bit thick, about the consistency of honey.
Notes
RECIPE TIPS
Use quality butter. You want these butter shortbread cookies to taste as good as possible.
Measure the flour properly. Too much will make dry shortbread and too little will cause the cookies to spread while baking. Fluff the flour with a spoon, spoon it into the measuring cup, and level off the top with a knife.
Bake the cookies on parchment paper. A silicone mat will cause the bottom edge of the cookies to spread a little.
