You might not know exactly what it is, but by now you might have heard of umami.
Because the flavour — described as the fifth basic taste after salty, sweet, sour and bitter — is starting to make an impact in the UK as a food condiment.
It is available as a paste and a powder and adds an intensely savoury note to dishes.
Demand for umami has grown by 25 per cent in the past year, partly down to celebrity endorsements from chefs like Jamie Oliver and Nigel Slater.
Discovered in Japan, it is present in a lot of Oriental cooking as well as foods as different as anchovies, Parmesan, soy sauce, Marmite, mushrooms, shellfish, Worcester Sauce and balsamic vinegar.
