When I cook pasta I add salt. This makes health conscious types shake their heads and say “tut” but I do it because I think it makes the water boil faster. I don’t know whether it actually does or not, but it should, and just believing that it does helps me pass the time.
I am stopping, however, as yesterday I accidentally dropped the whole salt mill into the water.
It is often said, and I can now confirm through personal experience, that putting your hand into a pan of boiling water really, really hurts.
