A series diode would almost work, except that it only cuts the power

The whole point was to get more power from the hot plate, without
burning it up. So you don't want to reduce the 240V power by a full
3/4, reducing it by 1/2 might be the ticket. Of course, doubling the
power would probably still melt the sucker.
