Kelle şekeri (literally, head sugar) is an irregular, compact ball of sugar you keep in your cheek to self-regulate the sweetness of your coffee or tea. Simply place a piece in between your cheek and front molars and allow your saliva and hot beverage do the rest. You no longer have to travel to eastern Anatolia to try this centuries old tradition. The Ace Hotel in midtown Manhattan serves Kelle şekeri in its lobby bar.
