Lightly flour a counter/worktop or some baking/parchment paper, and use a rolling pin to open up the shortbread dough to a rough rectangle or square shape, with a thickness of about 1-1½ cm ( ⅓– ⅔“). *Tip - use 2 sheets of paper to do this & keep the rolling pin clean). Use a flour dipped rectangular cookie cutter to cut out the shortbread, leaving moving the dough till you have finished cutting out. Pull back the excess dough, use a fork to 'Dock' the shortbread pieces, before carefully transferring to a prepared cookie tray with a palette knife. (See Photo 6 before this Recipe Card).
Traditionally, Scottish shortbread is made without a cutter and freehand, in biscuit ‘fingers’ or Petticoat Tail triangles. For Petticoat Tails, shape ⅓ of the dough into a ball then a flat disk, 1-1½ cm ( ⅓– ⅔“) deep, about 10cm (4″) in diameter. Cut into 6 triangles, 'Dock' the surface, and crimp the edges, by squeezing the dough between your thumb and index finger.
For simple shortbread fingers, shape the dough into a rough rectangle by hand, with a depth of 1-1½ cm (⅓– ⅔“). Trim the edges straight, and cut biscuit fingers about 1½ cm (⅔“) wide by 6¼ cm (2½” ) long. *Cut slightly thinner, as they puff a little on baking. Use the left-over scraps to make petticoat tails, or more fingers. Go over the cuts again if need be, as the cranberries and nuts make cutting not as easy. Again 'Dock' the shortbread fingers before placing on the tray, with at least 1½ cm (⅔“) gap in-between the biscuits.
