Western chefs are finally embracing umami. Formerly it was believed the human tongue could only taste four flavours - sweet, salty, sour and bitter. But the Japanese discovered monosodium glutamate and its umami flavour.

In 2000, scientists proved that the tongue had receptors for umami. And people in Britain will now be able to add the flavour to their food, thanks to start a new puree called Taste No. 5.
