It’s appetizing news for anyone who’s ever wanted the savory taste of meats and cheeses without actually having to eat them: chemists have identified molecular mechanisms underlying the sensation of umami, also known as the fifth taste.

The much-loved but historically unappreciated taste is produced by two interacting sets of molecules, each of which is needed to trigger cellular receptors on a tongue’s surface.
