essel itself, while the burner stays cool. Since there is no transfer of heat from burner to pan, there is virtually no wasted heat. Studies have shown that induction cooking may be up to 90% energy efficient, compared to electric and gas cooking, which are 47% and 40% energy efficient respectively. In addition to efficiency, induction cooking is the superior choice when it comes to safety issues. Because the cooking surface stays cool (i.e. room temperature) there are no more burned hands or hot pads and there is no open flame sending potentially dangerous fumes into the air. Best of all, with the heat focused in the right place, the kitchen--and the chef--stays cool and comfortable.
But the real luxury of induction cooking鈥攖he things that sets it apart as the Porsche of cook tops鈥攊s the precision and control it gives the chef. By varying the strength of the magnetic field, the heat generated in the pot responds instantly. This means water boils in half the amount of time it takes electric and gas stoves. Low temperatures work as well as high ones鈥攎eaning you can toss out your double boiler! One experiment showed chocolate chips melting at such a low temperature they held their shape until spread with a spoon. Induction warmers are great for caterers as well, since they hold low temperatures and keep food warm better than any of the alternatives.
Unfortunately there are a couple big disadvantages to induction stoves. For the pan to conduct energy it must be magnetic鈥攖hat is, it must contain iron. Therefore, cast-iron and steel pots and pans are necessary. Test your cookware by passing a magnet across the pan. If the magnet sticks, the pan will work. Some cookware, made with layers of aluminum and copper for distribution, will still work beautifully on an induction cook top, as long as the surface of the pan is steel.
The second disadvantage is unavailability. For some reason, induction cooking has been slower上一页 [1] [2] [3] 下一页
