Umami

For those of you, like me, who had never heard of Umami before Mal Anderson mentioned the word, when speaking of the rolled lamb on Thursday last, take a look at this; http://en.wikipedia.org/wiki/Umami.
Umami is the fifth taste, sweet, sour, salt, bitter and umami, meaning savouriness. There is an excellent article by Fennela Souter in this weekend's "Good Weekend" about taste and super taste. It's all about the number of taste buds we have and the density on the tongue. I'll try to obtain a copy; watch the Links box. Maybe we should have a W&F meeting with some chemical testing, to determine how many of us are "super tasters". Anyone have access to PROP (6-n-propylthiouracil)?
