The handle to the lid of our steamer has broken off. The contact area is
a narrow rim along a 12cm by 8cm oval. It is made out of plastic.

Does anyone have any pointers on what sort of adhesive would be
appropriate? It needs to withstand high temperatures (up to 100 degrees
Celsius) and should be non-toxic (food safe). You should be able get it
wet and stick it into the dishwater too.

Removing the lid with no handle on it tends to lead to scalding...

Thanks in advance,
