I response to original taste/flavour question... I think the difference may be in the way we use them.

I find I use flavour is most often used in two ways:
1) when describing the quality of what is being eaten. "it has a flavour reminiscent of cloves and thyme."
2) as a verb to signifying to add more taste or to season some food. "flavour a broth with cloves to make it a hearty and rich"

It is usually used in a positive sense. If it has a flavour, it’s good. Taste, on the other hand can be good or bad. Usually if something has a bad flavour we’ll say “this tastes bad.”

I don’t know if this helps you xara. My dictionary doesn’t make it any clearer as both words are used to describe the other.


(also, just to muddy the waters a little bit more, in my business, when we design a foam bath or shampoo, we create flavours instead of scents or aromas – I have NO idea why this is)
