Testing portable Induction Plate
I had heard such good things about induction cooking that I picked up an Aroma 1500 watt Induction hot plate at COSTCO. I thought it would introduce me to induction cooking and speed up heating water for coffee. Unfortunately, I had forgotten that much stainless steel is non-magnetic. Most of our cookware is Revere Ware and it doesn't work. However we had two kettles. One turned out to be non-magnetic as well but the other, while lighter, does work on the unit.
I was already considering returning the unit since I couldn't produce any other quickly available cook pots except my cast iron pans and dutch oven. However, I wanted to see if it was indeed faster. I tested several containers with 4 cups of cold tap water. I compared them with my Hamilton Beach electric kettle and found all convection methods to be slower rather than faster. My light weight kettle took 5:10 m:sec vs the 4:45 for the HB electric but other methods were slower still. I thought heavy iron might be best. I had a little old le creuset baby dutch oven that took 6 minutes and I tried a 10 inch cast iron skillet that took at least 7 minutes.
I choose the heavy iron items because of their extra iron and because they were all that I had available. Perhaps a heavier normal kettle would have given better results? Perhaps the extra time for the heavy iron is due to overcoming the specific heat of the metal while the light kettle had insufficient ferrous material to get maximum efficiency.
In any case, at least for quick heating, this unit is a failure. Does anyone have corrections or additions to my testing methods? Have I missed something obvious?
