A Toasty Tip!
(courtesy of The Pampered Chef)
Spread bread slices on a cookie sheet and place in the middle of your oven and bake until brown. About 10-15 minutes. Take out the cookie sheet and you will be able to tell where your over is hottest, and can compensate for that by turning the cookie sheet at the halfway point, or not putting cookies in the area where they seem to burn the most, etc.
