@holl - The tongue tastes (at least) six flavours: Sweet, bitter, sour, salty, umami and fatty.

@vattuvarg @holl @lupyuen You forgot "bad taste" and "exquisite taste" ;-)

@vattuvarg @holl @lupyuen Fatty? Isn't that a function of touch, and feeling viscosity and texture, rather than taste?

I mean, I'm no expert, but that's what I thought.

@Blort - That is exactly why it took so long to discover the fatty taste area.

Fast food and snack makers use compounds that trigger this area and have done so for years already. (A bit like monosodium glutamate is used for umami).
