Argh I'm afraid to say I wholeheartedly disagree with the fact that I can't identify cow dung as I haven't eaten cow dung. When I refer to tasting the cow dung in the Indian Balmadi. I am referring to the olfactory sensation I feel when I cup the coffee. Spraying the liquid over my pallete, and allowing the aroma and vapour to travel to my olfactory region.
Taste is purely the effect of the tastebuds, sweet, sour, umami etc. Flavours such as strawberry, or cow dung are infact determined in the olfactory region, which, when I smell cow dung, is the same region picking up the flavours.
Sorry for long winded response guys!
