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.

By law manufacturers must disclose the energy efficiency of their appliances, rated A to G. These are usually displayed prominently in showrooms. The better the rating, the more energy efficient the appliance is - good for both the environment and your pocket.

Rather than cause accidental heat-damage, prevent such damage in the first place:

• Always use a heat protection pad or trivet (with rubber feet) for hot cookware, or leave cookware to cool on the hob first. Never put hot pans, particularly cast iron. Such heat can damage any surface!
• If you must put a hot pan on the base of a sink use a protective sink mat, sponge, or cloth beneath. It is best to leave the utensil to cool slightly first, or put a few inches of cool water in the sink before the pan.
• Avoid pouring boiling liquids directly into sinks without turning on the cold tap as well.
