"Non-reactive titanium would work well for some things."

Titanium is FAR from being "non-reactive". What gives titanium metal parts relative inertness is the almost instantaneous formation of a very strong and tenacious oxide layer at the surface (like aluminum and magnesium, only more so).

Whatever it's called. As long as it doesn't turn my greens gray like aluminum does. And doesn't scrape off in the food easily like aluminum does.
