Recently I purchesed a Miele full inducion cooktop KM 7684 FL. One of the first pot sets I tried was the Le Creusts I brought back from the US. All seemed well until I tried to cook a steak in their Cast Iron frypan. It was "neatly" half cooked! i mean like one half was perfectly seared, the other barely off rare.
I conacted Milie to see if they had an issue with heat displacement on their cooktop, to which they advised nay. So I re-ran the cook and took a photo with my thermal camera that told the story. Unbelievabley, only half of the pan was hot on induction, the other not!. I guess when cast, the metal used was not from the same pour and inferior. So this is something new to me that would be very hard to experience if cooking on gas or a regular electric hot plates. Glad I have a thermal camera! (Im going to have to check the warrenty on those things) CS
Edit, corrected cooktop model number
