What's one of them taste of then*? Are we talking farmed or wild Umamis here?

I'll have my coat. I'm off to Waitrose for a box of oven-ready, breaded Umami pieces.

*Yes, I know, probably chicken.......

Not earth-shattering to say the least, but right in line with electronic noses to detect scents and perhaps dangerous substances, now there is an electronic tongue to apply the same principles to the sense of taste. Although its initial applications are commercial (to authenticate wines), it's not too hard to see its application extended to perhaps taste for toxic or contaminated drinks and so on.

it has to have a nose too, a spectrum analyser to view the colour, and a voice box to spout crap about "barrow loads of creosote" or whatever.
