Heat the oven to 400℉.
Lightly flour the top of the dough and roll it out into a rectangle roughly 6 x 9 inches (it should be somewhere between ½ to 1 inch thick once rolled out).
Then fold the dough into thirds, just like a business letter.
Lightly flour the board again (if necessary) and rotate the dough so that the smooth side faces to your left. Then repeat the process, rolling out the dough to a rectangle about the same size and folding it into thirds like a business letter, three more times (for a total of four times).
Roll out the dough to a 6 x 9 inch rectangle one last time, and then cut it lengthwise in half so you have two pieces, each measuring about 3 x 9 inches. Cut each length of dough into four pieces on the diagonal in order to form roughly even triangles.
Place the dough triangles, about an inch apart, on an ungreased baking sheet. (The dough will rise, but it will not expand sideways.)
Bake the scones for 15 to 20 minutes, or until the edges begin to crisp and the tops are golden brown. (Do not overbake. The scones will continue to cook a bit after being removed from the oven, and they taste best when still slightly moist and soft on the inside.)
