For Perfect Cookies
Cookie dough that is to be rolled is much easier to handle after it has been in a cold place 10 to 30 minutes.
This keeps the dough from sticking, even thought it may be soft. If not done, the soft dough may require more flour and too much flour makes cookies hard and brittle. In rolling, take out on a floured board, only as much dough as can be managed easily. Flour the rolling pin slightly and roll lightly to desired thickness. Cut shapes close together and keep all trimmings for the last. Place pans or sheets in upper third of oven. Watch cookies carefully while baking to avoid burning edges. When sprinkling sugar on cookies, try putting it into a salt shaker, It saves time.
