Cookery writer Laura Santtini has teamed up with Japanese restaurateur and chef Nobu Matsuhisa to launch a veggie umami paste.

Santtini’s original Taste #5 paste was launched in 2009 and has gone on to sell about half a million tubes. It uses ingredients including tomato, Parmesan and porcini mushrooms to impart umami, the so-called fifth basic taste.

Santtini is hoping to hit one million tubes with the launch of a vegetarian version. The garlic-based purée (rsp: £2.99) features ingredients high in umami, including miso, shiitake mushrooms and green tea.

It launched into Selfridges last week and is due to hit Waitrose at the end of April.
