Lime Snowball Cookies

1 1/2 cup unbleached flour
1/2 cup cornstarch
1 cup unsalted butter, softened to room temperature
1/2 cup confectioners' sugar
2 Tablespoons fresh lime juice
1 teaspoon fresh lime zest, finely grated
1/2 teaspoon lime oil (optional) or lime extract (optional)

1) Preheat oven to 350*.
2) In a medium bowl combine the flour and cornstarch and blend well. Set aside.
3) In a larger mixing bowl, using an electric mixer, beat the butter and 1/2 cup confectioners' sugar until light and fluffy.
4) Mix in the fresh lime juice, lime zest, and lime oil if using.
5) Beat in the flour mixture until smooth.
6) Refrigerate cookie dough until just firm, approximately 45 minutes.
7) Line two aluminum baking sheets with parchment paper.
8) Butter a measuring spoon and measure out a scant 1 Tablespoon of the dough. Form into balls and place on the prepared baking sheets. Space the cookies 1" apart.
9) Bake cookies for about 23 minutes or until browned on bottom and golden brown on top. Transfer the baking sheets to counter, and immediately sift with the remaining confectioner's sugar.
10) Cool the cookies completely on baking sheet.

Makes an estimated 2 1/2 dozen.
(Uses fresh lime juice and lime oil. If you cannot find lime oil, add more juice or zest.)
