I always enjoy the cooking shows and when I see the baking trays, I'm usually tempted to buy, but then I think of the baking tray I inherited that must be 70 or more years old. It's blackened with age and badly warped, but if I put a piece of greaseproof paper on top of it, nothing sticks and the heat is uniform all over, so the biscuits are evenly browned on the bottom. Why fix it if it ain't broke?!!
