I had an incident with the element in my brewing kettle where it went on without water. I discovered it reasonably quickly but by that point it was glowing bright orange and the straight stick shape distorted to form more of a V shape. I was able to bend it back to more or less the correct shape. The surface of the element is now discoloured to a brown with some black flecks.
It is working ok again now but is it ok/safe to use still? Any likely food safety issues do you think?
