Aroma Burners

Japanese aroma burners called Chakouro are usually used with green tea but it is possible to use something else according to taste.

They are very easy to use: a tealight candle is put inside the pot and lightened then a bit of green tea is added to the plate located on top of the pot. The green tea smell is going to spread through the room.
You can of course use black tea leaves instead of green tea according to your taste...
