Taste No. 5: Umami Paste

British food writer Laura Santtini created it.

"The product captures the elusive fifth taste (after bitter, salty, sour and sweet). Umami is named after the Japanese word for 'good flavor' and is best described as 'savory.' Made from tomatoes, anchovies, parmesan cheese and porcini mushrooms, this delicious paste can be squeezed into pasta sauces and risottos or rubbed on grilled meats and crostini for added depth," stated an unattributed review in last weekend's Wall Street Journal.
