1 cup softened unsalted butter
1/2 cup superfine sugar
2 cups all-purpose flour
1/4 cup cornstarch
1/4 tsp. salt
2/3 cup coarsely chopped dried cranberries
1/4 cup minced crystallized ginger
Line one large or two small baking sheets (to accomodate three 6-inch rounds) with parchment paper.
In a bowl with an electric mixer, cream the butter and sugar until light. With the mixer on low, add the dry ingredients slowly, and the cranberries and ginger, mixing just until crumbly. Transfer dough to a lightly floured surface. Gently knead until it just comes together. Divide dough into three balls and transfer to baking sheets, pressing each into a round about 6 inches in diameter. With a large, sharp knife, cut eacjh round into eight wedges. Do not pull sections apart. With a small knife, score the edges of each round to create a scalloped edge. With the tines of a fork, decoratively score the top of the dough. Chill for at least 15 minutes.
Preheat oven to 350 degrees.
Bake the shortbread for 25 to 30 minutes, or until edges are lightly browned. Let cool for 15 minutes and transfer to racks to cool completely. Shortbread can be cut into wedges while warm or kept in rounds to be cut at serving time.
