Like many people, my first introduction to halogen ovens was via the TV shopping channels. If I'm honest, I pretty much dismissed them without too much thought. A lot of the gadgets that you see on these TV channels tend to sound like a good idea but prove impractical in daily use.
It wasn't until my sister-in-law actually got one and shared her experience that I realized I had made a mistake in writing these ovens off. They offer all sorts of benefits to the user, and they're really easy to use and to keep clean (much easier than a conventional oven). Many of them have a "self cleaning" mode in fact.
Like many of the most successful innovations, halogen ovens are, when all's said and done, rather simple. They consist of a large glass bowl, into which the food to be cooked is placed, and a cover for the bowl.
The cover has a halogen light bulb, and sometimes some infrared elements also, and a fan. The halogen light bulb heats the air to a high temperature very rapidly and the fan circulates the heated air around the food to be cooked to ensure that it cooks quickly and evenly.
You can put a whole meal into a halogen oven at one go. For example, you can roast a chicken and cook all of the vegetables at the same time. The high temperature seals the flavors inside the food, so there's no flavor leakage from one item to the other. It's really convenient.
Halogen ovens heat up extremely quickly and the convection element means that food cooks very rapidly indeed. What you get is food that tastes like it's been roasted in an oven - but in almost as short a period of time as if you had cooked it in a microwave. It's the best of both worlds really.
