Matcha Shortbread Recipe II

Ingredients
2 cups bleached all purpose flour
1-2 tablespoon green tea powder (matcha — See Note 1)
1/2 teaspoon salt
1 cup butter (unsalted at room temperature — See Note 2)
1/2 cup powdered sugar (more if your tea is very intense)

Directions
Sift the flour, powdered tea and salt into a bowl.
In a mixer bowl, beat butter and powdered sugar until fluffy.
Add flour mixture to mixer bowl and mix slowly until dough just comes together.
Pull dough together carefully in a log, approximately 2 inches in diameter.
Wrap dough log and place in freezer for 30 minutes or until dough has firmed to the touch.
Slice dough into 1/4 inch rounds and place on a parchment or Silpat lined cookie sheet, approximately 1 inch apart.
Bake in a preheated 325 degree F oven for 16 to 18 minutes (or until the cookies are just starting to turn golden around the edges), turning the pan halfway through the baking time.
Remove cookies immediately from the cookie sheet and cool on a wire rack.
Store in an airtight container or wrap well and freeze.
The well-chilled cookie dough can also be rolled out and cut into desired shapes before baking.
NOTE 1-- powdered green tea is not merely green tea that has been pulverized in a food processor or food mill, it's a special kind of tea that has been prepared to dissolve nicely.
NOTE 2-- don't use the microwave to soften the butter, room temperature butter is the correct consistency for this recipe.
