The CookTek Cooktop is one of those amazing 21st century kitchen appliances that is as wondrous as the microwave was in the 1980s.
This device is a heating element--for lack of a better description--that remains cool even when it's heating food. Yes, that's right, it zaps the food with magnetic energy which heats a food-laden pan.
The freestanding cooktop plugs into a standard 120V power outlet and has a digital control used to set a precise heating temperature in Celsius or Fahrenheit or varying heat intensity like a stove element (one to 20).
CookTek claims it heats food faster, which is marginally true. Certainly it is faster than the old coil stove tops and as fast, if not faster, than gas stoves.
The downside is that the device won't work with all cookware. I have a non-stick Analon-brand cookset--that's made of a carbon composite material--and the system just beeped an error at me, though it worked fine with the demo pan that CookTek sent along. Of course CookTek wants you to buy their cookware with the system, though pans that are magnetic (steel, iron, nickel or various alloys) that you already own should work fine.
Ultimately this device is amazing, even if it is pricey. And, there are a variety of appliances, including wok systems, that use the technology. These products will certain draw interest from the gadget nuts that hang out in the kitchen.
