To keep the "twist" in the cheese straws, it is essential that they be very cold when they go into a very hot oven.
The standard size for one sheet of frozen puff pastry from a grocery-store box is 10 by 10 inches. If your puff pastry is not this size, cut the width to measure 10 inches.
Straws may be made 1 day ahead and kept, in an airtight container, at room temperature.
