Umami, billed as the ‘fifth taste’, was discovered by the Japanese in the early 1900s and is now recognised as a desirable savoury note in a whole raft of food products.
The new product is mysteriously called Taste No. 5, and is the brainchild of cook and food writer Laura Santini. It is made of a palate of Italian ingredients, including tomato, Parmesan cheese and porcini mushrooms.
