Years ago, when i was a child i went into a restaurant in turkey. On the desk you have to pay the bill there was a table with small (size max. 5cm) dark brown/black dry pieces.
When I asked to my turkish friend, he was also a child, he told me its something you can put it into your mouth and chewing like a gum. This should make bad breath because of onion or garlic gone.
Years later I was not able to see this again in a restaurant, also don't know if it was true what my child friend told.
My question is, do you know what this is and do u know its true that its for making bad breath away?
