Baking Cookies for the holidays? The simplest of kitchen gadgets may save the day, especially if that last tray of cookies gets overcooked, as last trays of cookies are wont to do, and the cookie bottoms burn and blacken. No tears. Just pull out your trusty grater, or if you have this antique handmade handled grater, all the better! Simply let the cookies cool down, rub the rough edge of the grater over the cookie bottom, and voilà! If you don't tell, I won't, and we're the only ones that will ever know that the cookies had a problem.
