Whilst buying perfume for my wife, the assistant kept offering us a glass of coffee beans to 'cleanse our olfactory palate' in between smelling fragrances.
I had heard of 'palate cleansing' before, but never thought of it in an olfactory way, nor heard of using the smell of coffee beans.
Now there is some mention of palate cleansers on the internet, but I wondered if there was a particular craft of 'palate cleansing' when eating particular foods - or even if particular types of palate cleansers existed for particular types of foods.
My question is: Are there particular palate cleansers for particular foods?
