NOTES FROM THE TEST KITCHEN
FORMING AND BAKING THE SHORTBREAD
1. Press the dough into a closed springform pan collar; smooth with the back of a spoon.
2. Cut a hole in the center of the dough with a 2-inch biscuit cutter and remove the round of dough—place it on the baking sheet next to the collar; replace the cutter in the hole.
3. Open the collar, but leave it in place. Bake 5 minutes at 450 degrees, then 10 to 15 minutes at 250 degrees.
4. Score the partially baked shortbread into wedges, then poke 8 to 10 holes in each wedge.
5. Return the shortbread to the turned-off oven to dry; prop the door open with a wooden spoon or stick.
