Innovations that go beyond the standard gas and electric options include:
Combination ovens: Combination microwave-convection ovens combine the speed of microwaving with the even cooking of convection baking.
Convection oven: A fan circulates hot air through this gas or electric oven, enabling food to cook faster and more evenly. Such even browning means superior results, especially when baking. Also, because the air circulates, more of the oven space can be used.
Halogen/microwave combination oven: These combine light waves with microwaves to cook food four times faster than a conventional oven would -- with the same oven-quality browning and crisping.
Microwave oven: These appliances use electromagnetic waves to cook and warm food in much less time than conventional ovens and stove tops -- a great convenience for time-pressed cooks.
