Solution for uneven heating on an electric coil stovetop I'm struggling to find a solution for my apartments coil stovetop and its uneven heating. I've never run into the problem until I started working on my holiday hard candy recently. I can't keep the coils heating consistently at high temperatures. I need to measure the temperature but I can't do that when it varies drastically across the pot.

Is there anything I can do to buffer the heat from the coil before it gets to the pan? 

I don't have any options for using a different stove so I need to make this work. I've considered some sort of heating stone that would help even the heat out but I figured that would take DAYS to heat up properly.
A copper diffuser plate will help spread the heat more evenly.

Is it possible the coils are not all touching the bottom of your pot?
