Most avid bakers prefer separate, even-heat double electric ovens. If that describes you - and you have the space - be sure one of the ovens is equipped with a broiler that provides at least 3,000 watts of cooking power. Also look for racks that pull all the way out and lock in place for safe, easy access to the oven. On the inside, a dark interior shows less baked-on grime, while a porcelain interior is easier to clean

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.

When you do have to shop for a new appliance, look for the Energy Star label. Energy Star appliances have been identified by the U.S. Environmental Protection Agency and DOE as being the most energy-efficient products in their classes. They usually exceed minimum federal standards by a substantial amount.
