Convection ovens allow you to bake more foods (cookies, muffins, etc.) at once with even browning, but without the need to shift and rotate pans. A convection oven is the same as a conventional oven except a fan is installed in the back interior of the oven. The fan is used to blow and force the heat to circulate in the oven and around the food, thus eliminating the need to rotate and shift pans. In reality, though, even with the most expensive convection ovens, you will still need to rotate your foods, because there will always exist still hot spots in the cavity, because the cavity is small. Don't compare home convection ovens with most commercial convection ovens used by bakers and small food manufacturers, because their commercial ovens are much larger than home ovens and commercial ovens don't have any hot spots and therefore, there's no need to shift and rotate pans.

An absolute must with a million and a half uses. But do not buy just any plastic wrap. Go to a restaurant supply store and buy a large roll of restaurant plastic wrap. It sticks much better than the common grocery store plastic wrap and is much cheaper per foot.

Do not add salt to the water when cooking sweet corn because the salt will toughen the corn. Add a little sugar to the water to boost the flavor.
