Shortbread Cookies:

2 cups (260 grams) all-purpose flour

1/4 teaspoon (2 grams) salt

1 cup (2 sticks) (226 grams) unsaltedbutter, room temperature

1/2 cup (60 grams) powdered (confectioners or icing) sugar

1 teaspoon (4 grams) pure vanilla extract

For Chocolate Dipped Shortbreads:

6 ounces (180 grams) semi sweet or bittersweet chocolate, finely chopped

Once you have made the basic shortbread batter, you can add about1/2 cup (90 grams) of chocolate chips to make chocolate chip shortbread, or add 1tablespoon of instant espresso powder for a coffee favor. All it takes to have a cinnamon flavored shortbread is to add 1 teaspoon ground cinnamon, or1 tablespoon of finely chopped orange or lemon zest will give you a nice citrus flavored shortbread. The texture of shortbread can also be changed by replacing 1/4 cup (35 grams) of the all purpose flour with rice flour which gives the shortbread a slightly crunchy texture. Or, for a more delicate tasting shortbread, with a melt-in-your-mouth texture, replace 1/2 cup (65 grams) of the all purpose flour with cornstarch (corn flour). Shortbreads can also be cut into various shapes and sizes using your favorite cookie cutter. They can also be baked in a tart pan, or baked in a rectangular pan and then cut into shortbread "fingers". If you like, dip the ends of the baked shortbread in melted chocolate as we have done here. Royal shortbread is the name given when one end of the baked shortbread is dipped into melted chocolate.

s:In a separate bowl whisk the flour with the salt.  Set aside.

In the bowl of your electric mixer (or with a hand mixer), beat the butter until smooth and creamy (about 1 minute). Add the sugar and beat until smooth (about 2 minutes).  Beat in the vanilla extract. Gently stir in the flour mixture just until incorporated.  Flatten the dough into a disk shape, wrap in plastic wrap, and chill the dough for at least an hour or until firm.  

Preheat oven to 350 degrees F (177 degrees C) with the rack in the middle of the oven.  Line two baking sheets with parchment paper.

On a lightly floured surface roll out the doughinto a 1/4 inch (.6 cm) thick circle.  Cut into rounds or other shapes using a lightly floured cookie cutter.  Place on the prepared baking sheets and place in the refrigerator for about 15 minutes. (This will firm up the dough so the cookies will maintain their shape when baked.) Bake for 8 -10 minutes, or until cookies are very lightly browned. Cool on a wire rack.

For Chocolate Dipped Shortbreads:Place 3 ounces (90 grams) of the finely chopped chocolate in a heatproof bowl and place it over a saucepan of simmering water. Once the chocolate has melted, remove it from the heat.
